Abstract
A chisel includes a blade and a first handle and second handle that are each rotatably coupled to the blade. The first handle forms a first channel adapted to receive a first side of the blade and the second handle forms a second channel adapted to receive a second side of the blade opposite the first side. The two handles are rotatable between an open and a closed position. In some cases, the two handles comprise a rotatable coupling such that the first handle and the second handle rotate with one another in opposite directions between the closed and open positions. The chisel further can have an over-center structure configured to impede rotation of the two handles from the closed toward the open position. In some cases, the two handles each form an interlocking component adapted to releasably couple the two handles when they are rotated to the open position.
