The jointer plane (also known as the try plane or trying plane) is a type of hand plane used primarily to straighten the edges of boards in the operation known as jointing. A jointer plane may also be used to flatten the face of a board.
These long hand planes are useful for trimming or straightening long pieces of wood, like boards or doors. A jack plane is slightly shorter than a jointer plane, with a length from 12 to 17 inches (30 to 43 cm).
