Japanese plane

From Wikipedia, the free encyclopedia

The Japanese plane or kanna (鉋, kanna^?) is a plane made from a block of hardwood with a shaped hole which takes the blade and chip breaker. The apparently simple design disguises a great deal of complexity.

The plane is operated in the opposite direction to a Western style plane, being pulled towards the user rather than pushed.
