Description

Technical Field

[0001] The utility model relates to the technical field of carving knives, in particular to an anti-rolling carving knife. Background Art

[0002] A carving knife refers to various cutting-edge steel carving tools, which have a wooden handle at the back. In order to be comfortable to hold in the palm, the handle is usually round. Some carving knives have an oval cross-section, some have a diamond cross-section, and the top is an oblique tip. The carving knives currently available on the market are very easy to roll when placed on the desktop after opening the sheath, and are easy to roll to the ground to damage the knife head or roll to the elbow to cause safety hazards. Although there are carving knives with hexagonal shanks on the market, they are not as comfortable to hold and flexible to rotate as round shanks because of their angular bodies. In order to improve the safety during carving, a carving knife is needed, but the existing carving knives still have the following shortcomings:

[0003] For example, the utility model with application number 202122725574.3 discloses a carving knife, in which the cutting part can withstand a greater cutting torque to ensure the strength of the carving knife. The waste passes through the two chip flow parts and flows out of the carving knife through the chip removal parts on the same side respectively. The chip removal is smoother, and good chip removal performance is maintained to avoid knife breakage due to chip blockage. However, similar to the comparative documents of the above-mentioned application, when the existing carving knives are used, since most of the carving knives are cylindrical, they are very easy to roll when placed on the desktop, which makes the carving knives dangerous during use, resulting in reduced practicality and reduced efficiency of use of the carving knives.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-rolling carving knife is proposed. Utility Model Content
