The circular arc knife is a kind of knife suitable for engraving radius arcs. When used on an engraving machine for wood, it can be used in many fields such as decorative carving and handicrafts. Unlike straight knives, arc knives are curved. And the front and rear openings on the knife are suitable for engraving curves such as circles and ovals.

V knife

A V-shaped knife is a tool used to depict three-dimensional carvings such as edges, corners, and unevenness. V-shaped knives are sharp V-shaped. Therefore, it can cut patterns with clear shapes and sharp lines. When engraving, it is necessary to pay attention to the fact that the head of the V-shaped knife should closely fit the cutting surface, and should not be perpendicular to the wood. This prevents the engraved edges from breaking, etc.
