Outdoor knife

Abstract

We offer an outdoor knife that allows you to perform tasks such as "cutting," "starting a fire," and "sharpening the blade" with a single tool, especially during emergencies like natural disasters or outdoor activities. [Solution] An outdoor knife characterized by having a fire starter and a cushioned sharpening tool fixed to the sheath.

Description

Technical Field

[0001] The present invention relates to an outdoor knife characterized in that a fire starter is provided on the sheath and an abrasive tool having cushioning properties is fixed thereto.

Background Art

[0002] Conventionally, there have been outdoor knives that store a fire starter as an accessory on the sheath or the handle of the knife and remove and use the fire starter during ignition work, and outdoor knives with a rough grinding stone attached to the sheath (see Non-Patent Document 1 and Non-Patent Document 2). In addition, there has been a kitchen knife cushion grinder (see Patent Document 1) that can grind a kitchen knife uniformly by attaching abrasive paper to a sponge body to give it cushioning properties, so that the abrasive paper changes its shape along the angle of the edge of the blade.

Summary of the Invention

Problems to be Solved by the Invention

[0004] These prior arts had the following problems. (i) The fire starter was designed to detach easily from the sheath or knife handle, which sometimes led to it being lost. (b) Because the whetstone fixed to the sheath is a hard, plate-like object, it is difficult to keep the blade and the whetstone in contact at a uniform angle when sharpening, and those with little experience in sharpening blades often cannot sharpen the blade evenly. (h) Because the knife sharpening cushion is a separate tool, it was easy to forget to carry it with me. This invention was made to solve these problems. [Means for solving the problem]

[0005] This outdoor knife is characterized by having a fire starter and a cushioned sharpening tool fixed to the sheath. [Effects of the Invention]

[0006] There's no need to worry about losing a fire starter or forgetting to carry a whetstone, and even those with little experience sharpening blades can sharpen them evenly. Therefore, being able to perform tasks like cutting, starting a fire, and sharpening with a single outdoor knife during emergencies such as disasters or outdoor activities significantly increases the chances of survival. [Brief explanation of the drawing]

[0007] [Figure 1] This is a side view of the knife with the sheath in place. [Figure 2] Figure 1 is a cross-sectional view of the outdoor knife cut along line AA. [Modes for carrying out the invention]

[0008] The following describes embodiments for carrying out the present invention. (i) Make a groove in the top of the outdoor knife sheath (2), apply adhesive to the groove, and then fit the fire starter (3) into it and secure it in place. (b) A commercially available cloth sandpaper with a grit of 800 is attached to a 2 mm thick sponge, which is a cushioning material (4b), to create a cushioning abrasive tool (4). (h) Cut out the polishing tool (4) to match the shape of the side of the sheath (2), apply adhesive to the side of the sheath (2), and attach the cushioning material (4b) of the polishing tool (4). The present invention has the configuration described above. When using the present invention to ignite a fire, the knife (1) is pulled out of the sheath (2), the spine of the blade (1a) is pressed against the fire starter (3), and sparks are generated by rubbing it vigorously. Furthermore, when sharpening a blade using the present invention, the knife (1) is pulled out of the sheath (2), and the edge portion of the blade (1a) is pressed against the sharpening tool (4) to perform the sharpening.
