The chisel (only) is used when drilling holes in the material or scraping off fine parts, and is an indispensable tool for processing along with saws and planes in Japan. It consists of a part of an iron knife and a part of a wood handle for grabbing the hand, and the part of the knife is narrowed down to make it easier for holes to make a long neck. The blade tip is made of forging metal into steel for cutting wood in the same way as a plane, and the Komi part that is inserted into the shell, neck, and handle with soft ground metal is formed.

There are various types of chisels, but depending on the application, it can be broadly divided into chisels (tataki only) and finishing chisel (shiage only). The tapping chisel is used when digging a hozo hole using a genius or a hammer, and it is made sturdy. In addition, in order to use it by hitting it, an iron ring called a crown is attached to the head of the handle. The finishing chisel is used to finish the part dug with a chisel and to finish fine parts where no plane can be applied. The handle is long because it is cut only with arm strength, and the cutting edge is sharp.

Since only the chisel can not double as a small size, it is necessary to prepare various blade widths. It is a tool that has so many types of tools that you can use as a set of 10 large and small pieces as a set of chisels, even if it is one of the chisels (Oiri only). In addition, it is a tool whose sharpness is scrutinized as a plane, and many masterpieces and master craftsmen were born.
