Don't do it (鐁∥鉇) - Don't do it

Japanese: やりがんな(鐁∥鉇) - やりがんな

A tool used to shave and finish the surface of wood, with a shallow triangular blade resembling the tip of a spear attached to a wooden handle. Until the appearance of the modern-day dai-ganna (base plane) at the end of the 16th century, it was simply called kanna or kana, but after that it came to be called yari-ganna. The Wamyōshō states that a kanna is used to shave the height and depth of the blade marks of a chiyo (adzep), and it is assumed that it was mainly used to shave large lumber for construction. It was therefore thought to have been used with both hands, with a tip of about 10 cm long and a handle of 50 to 60 cm long.

木材の表面を削り仕上げる工具で，断面が浅い三角状の槍の穂先に似た刃を木柄につけたもの。16世紀末といわれる現在の台鉋（だいがんな）の出現までは，単に加牟奈（かんな），加奈（かな）と呼ばれていたが，それ以後〈やりがんな〉と称するようになった。《和名抄》に〈鐁は釿（ちような）の刃跡の高下を削るもの〉とあり，主として建築用の大材を削ったものと推測される。したがって両手で用い，穂の長さ約10cm，柄の長さ50～60cmのものであったと思われる。
