A grooving plane. A plane used in carpentry to make a groove. For a groove less than 15 mm wide a small anazukikanna or ko-anazukikanna 小穴突鉋 often is used. The plane consists of a plane stock, kannadai 鉋台, which can be divided into two sections, and is connected by two regulating bolts to a guide that determines the distance of the groove from the edge of the block of timber. The plane stock is divided into two parts in order to facilitate the making of a hole to insert the wakibari 脇針, a special blade used to smooth the sides of the groove. Each section of the plane stock is fixed with a separate bolt. The cutting blade, kannami 鉋身, is adjusted according to the width of the groove. The base of the plane has a projection known as the daizura 台面 and the width of the daizura is the same as the width of blade. When making a groove that is narrow, for example 3 mm, a hard base made of rosewood, Chinese quince, Chaenomeles sinensis, or brass is used.
