Problems solved by technology

[0002] Existing wood carving knives of different models and styles each have an independent handle. Although such a design is simple in structure, because the blade of the carving knife is easily damaged and it is an inseparable whole with the handle, a good handle is also Woodblock knives are scrapped due to broken blades, making hand-carving cost-prohibitive and wasteful from discarded handles

At the same time, various styles and models of wood carving knives with independent handles are also inconvenient to carry due to their large total volume and total weight.

[0003] To avoid the above-mentioned problems, it is necessary to make the wood carving knife and its handle detachable, but it is necessary to achieve a fast connection, quick disassembly and replacement between the two, and a stable, firm, and non-loose connection between the two. In combination, this is a problem that those skilled in the art have been eager to solve but have not been able to thoroughly solve for many years
