Lit. "bottom-cleaning chisel." A chisel designed to clean out the wooden shavings which have accumulated in the base of the hole during the process of carving out a mortise with a striking chisel *takakinomi 叩鑿. This chisel has no capping hoop, katsura 冠. The shank bends round in a curve towards the cutting blade, which is tipped with a hook, making it easier to scrape up shavings.
