tsukinomi 突鑿
KEY WORD : architecture / tools
A paring chisel that shaves a timber entirely by hand pressure. Chisels called *tatakinomi 叩鑿 are struck with a hammer. The tsukinomi has a longer handle and a longer blade than the tatakinomi, and there is no capping hoop at the end of the handle, which is usually made from rosewood or ebony. The cutting blade also has a sharper angle, generally about 20 degrees.
The paring chisel is used for finishing deep mortise holes and the surfaces of spliced joints. The blade-width varies, but some tsukinomi may be as long as 55mm.
