Description

[0001] The invention relates to a cutting device according to the features of the independent claim.

[0002] Touring skis are well-known pieces of sports equipment designed for ascending mountains by fitting climbing skins to their base. These skins are typically attached using mounting hardware at the tip and tail of the ski, as well as by fully but removablely gluing them to the base. For an efficient and safe ascent, it is essential that the shape of the climbing skins matches the shape of the skis. It is particularly advantageous if the climbing skin is shaped in such a way that the ski's edge, usually a steel edge, remains unobstructed. This allows the ski's edges to be used effectively even during the ascent.

[0003] Touring skins are usually manufactured with a certain excess and then trimmed to fit the touring skis. While the manufacturer can easily trim touring skins using industrial cutting machines, individual, manual adjustments without such industrial cutting tools are often very difficult.

[0004] Manually trimming a touring skin is usually done by attaching it to the touring ski. The excess skin extending beyond the ski can then be cut off, for example, with a knife. However, touring skins have a multi-layered construction, consisting of a backing layer with a skin or skin-like layer on one flat side and an adhesive layer on the other. When manually cutting with a knife, the adhesive layer often mixes with the fibers of the skin layer, causing the knife to stick and resulting in an uneven cut. Precise adjustment to the shape of the touring ski with a knife is only possible if it is guided along the outer edge of the ski.With this type of cut, the edge area is not left out by the touring skin, but remains covered by the skin, which means that the use of the edges during the ascent described above is not possible.

[0005] As an alternative to using a simple knife, there are hand-operated cutting devices that can be manually pulled along the edge of the touring ski. These devices typically consist of a blade with a support bracket, which, during trimming, extends between the touring ski and the climbing skin. As the cutting device is moved along the edge of the ski, the support bracket lifts the climbing skin from the ski's base and presses it against the blade. A problem with these devices is that, in practice, the support bracket between the climbing skin and the ski comes into contact with the adhesive layer of the climbing skin, which hinders the cutting motion and consequently leads to an uneven cut.

[0006] The object of the invention is now to overcome the disadvantages of the prior art and in particular to create a cutting device for trimming touring skins that enables efficient trimming of touring skins.

[0007] This preferably includes the ability to trim easily, quickly, and with high cutting precision. It also preferably includes the cutting device being of a simple and robust design.

[0008] The object of the invention is solved in particular by the features of the independent claim.

[0009] A cutting device for trimming touring skins is disclosed, comprising: . - a first guidance area that defines a first level for the surface guidance of the cutting device on the skin surface of the touring ski, - a second guide area that defines a second plane for guiding and aligning the cutting device along the side edge of the touring ski.

[0010] Preferably, the first guide area and the second guide area define a cutting channel running along the cutting direction.

[0011] Preferably, the cutting channel has an L-shaped guide profile composed of the first level and the second level.

[0012] Preferably, a blade is provided that projects from the first level into the cutting channel.

[0013] Preferably, a trimming gap is provided between the blade and the second level.

[0014] Preferably, the blade is designed to project freely and extend from the first plane to its projecting end, and to have a cutting edge with a cutting contour on its side facing the cutting direction.

[0015] Preferably, the blade has a blunt guide area at its projecting end for guiding or positioning along the lower edge of the touring ski.

[0016] Preferably, the trim distance is greater than 0.5 mm.

[0017] Preferably, the trim distance is less than 5 mm.

[0018] If necessary, the trim distance is designed to be smaller than the width of the lower edge of the touring ski.

[0019] If necessary, the cutting contour is designed to be crescent-shaped.

[0020] If necessary, the cutting contour is designed to have a point at its projecting end.

[0021] If necessary, the cutting edge is designed to point towards the first plane, particularly along its entire cutting contour.

[0022] If necessary, the cutting contour and the first plane may enclose a blade angle α that is less than 90°.

[0023] If necessary, the first guide area is designed to act as a counter-holder for the blade.

[0024] If necessary, the blade is designed to protrude from the first plane by a cantilever measured perpendicular to the first plane.

[0025] If necessary, the overhang is designed to be equal to or greater than the thickness of the touring skin to be trimmed.

[0026] If necessary, the cant measurement is intended to be between 0.8 mm and 5 mm, depending on the thickness of the touring skin to be trimmed.

[0027] If necessary, an adjustment device for adjusting the cantilever dimension is provided.

[0028] Optionally, the cutting edge may have a cutting edge, two flank surfaces converging at a cutting angle β towards the cutting edge, and a cutting axis running along the angular perpendicular of the cutting angle β through the cutting edge.

[0029] If necessary, the cutting axis is designed to run at an angle γ to the cutting direction, measured in the first plane.

[0030] If necessary, the cutting axis is designed to run at an angle γ of 0° to 45°, viewed in the cutting direction, away from the second plane.

[0031] If necessary, the cutting axis is designed to run at an angle γ of 20° to 30° away from the second plane when viewed in the cutting direction.

[0032] If necessary, the cutting axis is designed to run at an angle γ away from the second plane when viewed in the cutting direction, which is essentially half the cutting angle β.

[0033] If necessary, the angle of attack γ of the cutting axis is selected so that the cutting device is pulled towards the edge of the touring ski by the blade during trimming.

[0034] If necessary, the blade is designed to run at an angle of inclination δ relative to the first plane, as considered in the normal plane of the cutting direction.

[0035] Optionally, the blade is provided to run parallel to the second plane at an angle of inclination δ of 90° or to be inclined at an angle of inclination δ between 90° and 20°, in particular between 40° and 60°, from the first plane towards the second plane.

[0036] If necessary, a slot is provided between the first guide area and the second guide area, particularly in the second level, to accommodate the excess touring skin to be trimmed.

[0037] If necessary, the slot is designed to pass straight through the cutting device along the cutting direction.

[0038] If necessary, the cutting device is designed as a manually operated hand tool.

[0039] Optionally, the cutting device may have a support surface for the hand, and in particular for the thumb of the user, wherein the normal vector of the support surface is inclined towards the cutting channel and in the cutting direction.

[0040] If necessary, the cutting device for trimming the touring skin by selectively guiding the cutting device along both edges of the touring ski and along the skin line of the touring skin has two symmetrically arranged first guide areas, second guide areas, cutting channels, L-shaped guide profiles and blades.

[0041] The fur line corresponds to the laying direction of the fibers of the touring skin, i.e., in particular the gliding direction of the touring skin, which usually runs from front to back.

[0042] If necessary, the two first guide areas are designed to be at a certain angle to each other, thus pointing away from each other.

[0043] The use of the cutting device for trimming touring skins is also revealed by guiding the cutting device along a cutting direction that follows the edge of a touring ski.

[0044] In all embodiments, it is preferred that the touring skin is trimmed while the touring skin is attached to the touring ski.

[0045] The cutting device comprises a first guide section. This first guide section can be guided on the skin surface of the touring ski. In particular, the first guide section is guided along the skin nap of the touring ski's skin surface. Due to this planar guidance, the cutting device can only be moved along two degrees of freedom. The first guide section can be larger than 10 mm transversely to the cutting direction, preferably larger than 20 mm, and optionally larger than 30 mm. The first guide section can be longer than 20 mm along the cutting direction, preferably longer than 30 mm, and optionally longer than 40 mm.

[0046] The second guide section guides the cutting device along the side edge of the touring ski and aligns the cutting device along this side edge. The second guide section can be longer than 20 mm along the cutting direction, preferably longer than 30 mm, and optionally longer than 40 mm.

[0047] When the cutting device is pressed against the touring ski and climbing skins using the first and second guide areas, only one degree of freedom remains: that along the cutting direction and along the edge of the touring ski. This ensures good and safe guidance of the cutting device along the desired cutting direction.

[0048] The first and second guide areas define a first and a second plane. They form a cutting channel with an L-shaped guide profile, this L-shaped guide profile being composed of the first and second planes. This angled design, as described above, enables reliable guidance along the edge of the touring ski. The first and second guide areas are preferably rigidly connected to each other during trimming. Preferably, the first and second planes are perpendicular to each other. Preferably, the first and second planes run along the cutting direction.

[0049] The edge of the touring ski preferably runs longitudinally with a certain curvature and is not linear, in order to form a modern, sidecut ski. The cutting device allows the touring skin and / or its overhang to be trimmed along this curved contour and / or edge.

[0050] The cutting channel is preferably a free-flowing channel in which the touring skis, along with the climbing skins, are guided during trimming. Due to the special design of the cutting device, a counter-holder that runs along the adhesive surface of the climbing skin is unnecessary.

[0051] The blade now extends from the first layer into this cutting channel. It enters the skin from the outside, through the skin's surface, and preferably also passes through it. To prevent damage to the base of the touring skis, the blade is positioned at a certain trimming distance from the second layer. This trimming distance is preferably smaller than the width of the ski's lower edge. This trimming distance allows the skin to be trimmed in such a way that the edges of the touring skis are exposed, enabling their use during ascents. By appropriately limiting the trimming distance, the tip of the blade is positioned in the area of ​​the lower edge of the touring ski, which is usually made of stainless steel, and not in the area of ​​the soft plastic base.To ensure that the blade's edge does not damage the touring ski, the blade may have a blunt guide section at its projecting end for guiding it along or on the lower edge of the touring ski. This blunt guide section is preferably a flattened area of ​​the blade itself.

[0052] Preferably, the cutting edge of the blade points towards the first plane. In particular, the blade angle between the cutting contour and the first plane is less than 90°. When trimming, this has the effect that the cutting edge of the skin pulls the skin towards the first plane and thus towards the first guide area. In this design, the first guide area can therefore act as a counter-holder. However, the first guide area rests against the skin surface and not against the adhesive surface, so that the counter-holder cannot adhere to the adhesive of the skin. Rather, only the sharp blade protrudes into the adhesive layer of the skin. In addition, the cutting device, and thus also the first guide area, is preferably moved along the grain of the skin, which minimizes friction between the first guide area and the skin.

[0053] In principle, a configuration with a blade angle of 90° or more is also conceivable. With a blade angle of 90°, the climbing skin is neither pressed towards the first guide area nor towards the edge of the touring ski during cutting, thus enabling a neutral cut. With a blade angle greater than 90°, the cutting edge of the blade points away from the first plane and therefore towards the bottom edge of the touring ski. In this case, the bottom edge of the touring ski acts as a counter-support. Due to the robust design of the Unerkannte, the blade, especially with its blunt guide area, can be guided on or along the bottom edge of the touring ski to produce a clean cut.

[0054] Preferably, the blade is a rigid blade that protrudes rigidly into the cutting channel during trimming.

[0055] According to an alternative embodiment, the blade can be a movable blade, for example a rotary blade, in particular a round, rotatably mounted blade. With such a rotary blade, the blade angle is greater than 90°. The mounting of a rotary blade within the base body of the cutting device can be achieved by a rotatably mounted axis. The cutting edge has a cutting edge and two flank surfaces that converge at a sharp angle to the cutting edge. The angular perpendicular to the cutting angle of the flank surfaces corresponds to the cutting axis of the edge. A symmetrical arrangement can be used, in which the cutting axis essentially coincides with the length of the blade. However, asymmetrical configurations are also possible, where, for example, the cutting edge is only ground on one side, so that one flank follows the length of the blade and the other is ground at an angle to it.

[0056] A cutting device is now revealed in which the cutting axis runs at a certain angle of attack. The angle of attack is considered in the first plane. By changing the angle of attack, the cutting axis can be set to a neutral position or tilted, so that the cutting device is steered to a certain extent during trimming.

[0057] Preferably, the angle of attack is chosen such that, during trimming, the cutting device is pulled or pushed towards the edge of the touring ski by the angled blade, or cuts neutrally. The cutting axis preferably runs at an angle of attack of 0° to 45° in the cutting direction, away from the second plane, i.e., towards the edge of the touring ski. This angle of attack is preferably between 20° and 30°. In particular, however, the choice of the angle of attack depends on the cutting angle of the blade.

[0058] Preferably, the angle of attack is chosen such that it corresponds essentially to half the cutting angle. This means that the flank surface of the cutting edge that is further away from the second plane runs essentially along the cutting direction and is therefore essentially neutral. The flank surface that is closer to the second plane runs away from the second plane and thus towards the edge. While the normally oriented flank surface produces a clean cut, the inclined flank surface can cause a slight steering of the cutting device towards the edge of the touring ski. This allows for safer and easier guidance of the cutting device along the edge of the touring ski.

[0059] Alternatively, the cutting axis can run neutrally along the cutting direction.

[0060] A cutting device is disclosed in which the blade runs at a certain angle of inclination relative to the first plane. The angle of inclination is considered in the normal plane of the cutting direction. Preferably, the angle of inclination can be, for example, 90°, so that the blade runs essentially parallel to the second plane. Alternatively, the blade can also be inclined, so that the angle of inclination is, for example, between 20° and 90°, preferably between 40° and 60°. This provides the touring skin with a chamfer on its outer edge. If, in addition to such an inclination at a certain angle of inclination, the cutting axis is oriented at an angle away from the second plane, as described above, then the angle of inclination causes the cutting device to be pulled or pushed obliquely towards the top and side edges of the touring ski by the blade during trimming.

[0061] Preferably, a slot is left open between the first and second guide areas. During trimming, the excess skin can protrude into this slot. The slot preferably runs in the second plane and in the area of ​​the transition between the second and first planes. The slot preferably runs along the cutting direction, in particular through the entire cutting device. Optionally, the slot runs along the cutting direction through the cutting device but ends behind the blade when viewed in the cutting direction. This allows the trimmed excess to be carried away laterally.

[0062] Preferably, the two overhangs extending beyond the edges of the touring ski are removed by moving the cutting device in the same direction. This direction preferably corresponds to the direction of the skin's nap. For this purpose, the cutting device is preferably symmetrically designed and comprises two symmetrically arranged first guide areas, second guide areas, cutting channels, L-shaped guide profiles, and blades. This allows the touring skin to be trimmed either by guiding the cutting device along one edge or the other, preferably cutting along the skin's nap in both cases.

[0063] In this symmetrical configuration, the first two guide areas can be positioned at a certain angle to each other, pointing away from one another. This allows the blade on one side to lift from the surface of the skin when the first guide area on the other side is guided against the skin's surface, and vice versa.

[0064] Preferably, the second guide area and the first guide area are rigidly positioned opposite each other during trimming. Preferably, the second guide area and the first guide area are rigidly connected to each other. Preferably, the second guide area and / or the first guide area is a rigid guide element such as a guide plate or a guide rib.

[0065] The second guide area may optionally have two support projections for guiding and aligning the cutting device on a curved edge. For example, the guide rib includes two cams that project towards and towards the edge during trimming.

[0066] Preferably, the cutting device has a base body, which is in particular rigid. This base body can, for example, be made of plastic and, in particular, be an injection-molded part. The base body can form the elements of the first guide area, the second guide area, and optionally a part of the adjustment device. The base body can, for example, be formed in one piece. Preferably, at least one blade is attached to this base body.

[0067] The blade can be designed, for example, as a replaceable blade, particularly a replaceable hook blade. Alternatively, the blade can be a standard, commercially available blade, such as a standard trapezoidal blade or a standard hook blade. This means that when the blade becomes dull, only the blade itself needs to be replaced, not the entire cutting device, which has a positive impact on the durability and efficiency of the cutting device.

[0068] Preferably, the blade is designed as a replaceable blade. This replaceability is achieved, for example, via an adjustment mechanism. In particular, the locking means used to secure the blade can also allow for complete release of the blade and thus blade replacement.

[0069] When using a symmetrically designed, commercially available interchangeable blade and / or hook blade that has two cutting edges, it may be necessary to turn the blade over so that the other cutting edge of the interchangeable blade protrudes into the cutting channel if the previously used cutting edge is dull.

[0070] The blade holder and / or the adjustment device is preferably designed in such a way that the blade can be changed and, in the case of a symmetrically designed interchangeable blade, reversed.

[0071] In the case of two cutting channels, both blades can preferably be designed to be replaceable and / or reversible.

[0072] In subsequent sections, details of the cutting device will be described using the figures. Fig. Figure 1 shows a schematic top view of a cutting device when trimming a touring skin on a touring ski. Fig. Figure 2 shows a schematic top view of a cutting device in which the cutting direction is projecting. Fig. Figure 3a shows a schematic view of a detail of the blade, with the image plane running parallel to the second plane. Fig. Figure 3b shows a schematic view of a detail of a blade, with the image plane running parallel to the first plane. Fig. Figure 3c shows a schematic view of a detail of the blade, with the cutting direction projecting.

[0073] Unless otherwise specified, the reference symbols in the figures correspond to the following components: Touring skin 1, Touring skin overhang 1', Edge 2, Side edge 2', Bottom edge 2", Touring ski 3, Cutting direction 4, First guide area 5, First plane 6, Second guide area 7, Second plane 8, Cutting channel 9, L-shaped guide profile 10, Blade 11, Trim distance 12, Projecting end (of the blade) 13, Cutting edge 14, Cutting contour 15, Blunt guide area 16, Overhang 17, Adjustment device 18, Cutting edge 19, Flank surface 20, Cutting axis 21, Slot 22, Contact surface 23, Blade angle α, Cutting angle β, Angle of attack γ, Inclination angle δ

[0074] Fig. Figure 1 shows a touring ski 3 on whose base a touring skin 1 with a skin overhang 1' is attached. The touring ski 3 comprises an edge 2 with a side edge 2' and a bottom edge 2". The bottom edge 2" is the edge that is essentially flush with the base of the touring ski 3. The side edge 2' is the section of the edge 2 that runs along the side of the touring ski.

[0075] The cutting device allows the excess skin 1' to be cut off. For this purpose, the cutting device is moved along a cutting direction 4. The cutting device is preferably moved manually, preferably with a support surface 23 for the user's hand or thumb.

[0076] Preferably, the cutting device is symmetrically constructed and comprises two cutting channels 9 and two blades 11. This allows the overhang 1' of the touring skin to be trimmed on one edge 2 with one blade 11 and the overhang 1' of the touring skin on the other edge 2 of the touring ski 3 with the other blade 11. Due to the symmetrical design, both trimming operations can be performed in the same direction. In particular, it is preferred that the cutting proceeds from the tip of the ski 3 towards the tail. This offers the advantage of being able to cut in the direction of the skin's nap. This reduces friction between the cutting device and the touring skin 1 and also allows for a clean cut edge.

[0077] The edge 2 runs lengthwise along the touring ski 3, preferably with a certain curvature and, in particular, not linearly, as is common with modern, sidecut skis. The cutting device allows the touring skin 1 and / or its overhang 1' to be trimmed along this curved contour or edge.

[0078] Fig. Figure 2 shows a schematic view of a cutting device during the trimming process, in particular the cutting device made of Fig. 1.

[0079] The touring ski 3 is fitted with a touring skin 1 on its base. The touring skin 1 has a certain overhang 1' which is to be cut or trimmed by the cutting device. The touring ski 3 has an edge 2 with a side edge 2' and a bottom edge 2". The cutting direction 4 runs in the illustration of the Fig. 2 projecting from the picture plane towards the viewer.

[0080] The cutting device comprises a first guide area 5. This first guide area 5 is designed to guide the cutting device on the surface of the climbing skin 1. The surface of the climbing skin 1 refers to the outer side of the skin layer. The first guide area 5 defines a first plane 6. This configuration allows for planar guidance of the cutting device on the outer surface of the climbing skin 1.

[0081] The cutting device comprises a second guide area 7. The second guide area 7 enables guidance and alignment along the side edge 2 of the touring ski 3. The second guide area 7 is optionally designed as a rib in all embodiments and extends along the cutting direction 4. The second guide area 7 defines a second plane 8.

[0082] This configuration defines a cutting channel 9 with an L-shaped profile 10. The L-shaped profile 10 allows the cutting device to be guided precisely along the edge 2.

[0083] Preferably, the cutting channel 9 is bounded on two sides by the first guide area 5 and the second guide area 7. Preferably, the cutting channel 9 is open in the other two directions, i.e., towards the touring ski 3. Optionally, in all embodiments, an element can be provided that forms a counter-guide on the opposite side of the touring ski 3, i.e., on the upper surface of the touring ski 3. In any case, it is advantageous if the cutting channel 9 is kept free of any elements that come into contact with the adhesive layer of the touring skin 1 over its entire surface or that project between the touring skin 1 and the touring ski 3. An exception to this is the blade 11, which is intended to cut the touring skin 1, including its adhesive layer, along the cutting direction 4. However, this blade projects transversely into the touring skin, perpendicular to the adhesive layer.

[0084] Advantageously, after trimming the overhanging skin 1', a lower edge 2" should be at least partially exposed. For this purpose, a trimming gap 12 is maintained between the second level 8 and the blade 11, as shown in particular in Fig. 3c is described further.

[0085] Preferably, the blade 11 projects from the first guide area 5 and through the first level 6, extending from there into the cutting channel 9. Preferably, the blade 11 is the only element of the cutting device that projects into the cutting channel 9. The blade 11 is preferably arranged to project freely.

[0086] The blade, with its projecting end, preferably extends a certain overhang 17 from the first level 6 into the cutting channel 9. The overhang 17 is preferably chosen to correspond essentially to the thickness of the climbing skin 1. Typical thicknesses of climbing skins 1 are between 0.8 and 2.5 mm.

[0087] To adjust the cantilever length 17, an adjustment device 18 is preferably provided. For example, the blade 11 has mounting holes through which locking elements such as screws can be inserted. The holes can have a certain oversize so that the position of the blade 11 can be changed when the locking elements are open and fixed by tightening the locking elements. If, however, the cutting device is used exclusively for cutting climbing skins of a specific thickness, the adjustment device 18 can be omitted.

[0088] Preferably, a slot 22 is provided between the first guide area 5 and the second guide area 7. During trimming, the excess skin 1' can project into this slot 22. The slot 22 is positioned such that the excess skin 1' can project into it substantially flush with the rest of the skin 1. In particular, the slot 22 is provided in the second level 8 and runs along the cutting direction 4 through the cutting device. The slot 22 can also serve to transport away the cut excess skin 1'.

[0089] In all embodiments, the slot 22 can widen to form a receiving space. A support structure can be arranged around this receiving space in an arc-shaped or arm-shaped manner, connecting the second guide area 7 with the first guide area 5.

[0090] Preferably, the second guide area 7 is rigidly connected to the first guide area 5. An adjustment mechanism may optionally be provided. During trimming, the second guide area 7 is preferably rigidly connected to the first guide area 5.

[0091] In the present embodiment, the cutting device has a rigid base body. This base body can, for example, be made of plastic and, in particular, be an injection-molded part. The base body can, for example, be formed in one piece.

[0092] The base body can form the elements first guide area 5, second guide area 7 and optionally a part of the adjustment device 18. At least one blade 11 is attached to the base body. In all embodiments, the blade can be, for example, a commercially available interchangeable blade, in particular a hook blade.

[0093] As with Fig. 1 The cutting device is preferably symmetrically constructed and comprises two cutting channels 9 and two blades 11. The two first guide areas 5 can point away from each other at a certain angle. This allows the blade on one side to be lifted from the surface of the tour case when the other blade is in use, and vice versa.

[0094] The Fig. 3a, Fig. 3b and Fig. Figure 3c shows schematic views that can be used to describe possible details of cutting geometries. These are the preferred cutting geometries.

[0095] Fig. Figure 3a shows a schematic side view, with the image plane running parallel to the second plane 8. The blade 11 projects into the cutting channel 9. The blade 11 comprises a cutting edge 14 with a specific cutting contour 15, which in the present embodiment is curved and, in particular, crescent-shaped.

[0096] Furthermore, the projecting end of the blade preferably has a point. This point makes it possible to pierce the climbing skin 1.

[0097] The blade of the present embodiment preferably comprises a blunt guide area 16. This blunt guide area is provided at the projecting end 13 of the blade 11.

[0098] The blunt guide area 16 is suitable or designed to be guided at or along the lower edge 2". The blade 11, or rather its cutting edge 14, is inclined by a certain blade angle α.

[0099] In the present embodiment, the blade 11 is oriented such that its cutting edge 14 points towards the first plane 6. The blade angle α is less than 90°. The blade angle α is measured in the second plane between the first plane 6 and the cutting contour 15 and / or the average path of the cutting contour 15. This configuration has the advantage that the climbing skin is pushed or pulled by the blade 11 towards the first plane 6 during the cutting process. This allows the first guide area 5 to act as a counter-support during cutting. Furthermore, an acute-angled cutting gap is formed.

[0100] However, an alternative design is also conceivable in which the blade angle α is 90° or greater. With a blade angle α of 90°, a neutral cut would be made, essentially without a counter-support. With a blade angle α greater than 90°, the touring skin 1 would be pressed towards the lower edge 2 of the touring ski 3, with the edge 2 of the touring ski 3 potentially acting as a counter-support. The blade 11 could be guided along the lower edge 2" via the blunt guide area 16.

[0101] Fig. Figure 3b shows a schematic view, with the image plane essentially parallel to the first plane 6. The blade 11 comprises a cutting edge 14 with a cutting edge 19, which also forms the cutting contour 15. The cutting edge 14 also includes two flank surfaces 20, which extend at an acute angle towards the cutting edge 19. The flank surfaces 20 are at a specific cutting angle β to each other. The perpendicular bisector of the cutting angle β gives the cutting axis 21 of the cutting edge 14.

[0102] In the present embodiment, the cutting edge 14 is symmetrically designed and the cutting axis 21 coincides with the contour of the blade 11. However, a deviation can occur with an asymmetrical grind.

[0103] The cutting edge 14 can now be arranged with a specific angle of attack γ. In the present embodiment, the angle of attack γ is selected such that the cutting edge, or rather the cutting axis 21, extends away from the second plane 8 by the angle of attack γ when viewed in the cutting direction 4. This configuration causes the cutting axis 21 to point towards the edge 2 of the touring ski 3. As a result, the cutting device is guided stably along the edge 2 during trimming.

[0104] According to a preferred embodiment, the angle of attack γ is selected such that the flank surface 20 located further away from the second plane 8 runs substantially along the cutting direction 4. The flank surface 20 located closer to the second plane 8 preferably runs in a direction away from the second plane 8. The flank surface 20 running substantially along the cutting direction 4 enables a clean cut. The angled flank surface 20 serves to guide the blade along the edge 2 of the touring ski 3.

[0105] Fig. Figure 3c shows a schematic representation of cutting geometry details, with the cutting direction 4 projecting. The blade 11 projects from the first plane 6 into the cutting channel 9. This cutting channel 9 has an L-shaped guide profile 10 formed by the first plane and the second plane 8.

[0106] Preferably, a trimming gap 12 is maintained between the blade 11 and the second level 8. This trimming gap 12 makes it possible to expose part or all of the lower edge 2" during trimming.

[0107] The blade 11 projects a certain overhang 17 from the first level 6 into the cutting channel 9. The overhang 17 preferably corresponds to the thickness of the climbing skin 1.

[0108] The blade 11, or rather its cutting edge 14, can be inclined at a certain angle γ. In the present embodiment, the blade 11 is inclined outwards at an angle γ. This allows the climbing skin 1 to be chamfered during trimming.

[0109] Alternatively, the angle of inclination can also be, for example, 90°, so that a straight edge of the climbing skin 1 is formed. Preferably, however, the angle of inclination is between 90° and 20°. The angle of inclination γ is preferably measured in a normal plane to the cutting direction 4.

[0110] The projecting end 13 of the blade 11 is preferably positioned such that it is guided in the area of ​​the lower edge 2". This prevents damage to the running surface of the touring ski 3. Optionally, the blade 11 includes a blunt guide section 16 at its projecting end 13. This can be guided along or on the lower edge 2 of the touring ski 3.
