ABSTRACT:
A circle cutter having an elongate body is disclosed, the body having an awl perpendicularly affixed to one end and a crank handle affixed to the other. The crank handle stands out from the same face of the body as the awl's handle, and parallel to its axis. The awl's bit projects, coaxial with its handle, from the body's opposite face. A cutting block is disposed in a channel in the cutter's body and is variably positionable therealong. One embodiment of the cutter includes a slot in the channel through which the shank of a thumbscrew projects for tightening the cutting block into a fixed position. Another includes a detent ball in the cutting block, the ball being able to engage one of a regularly-spaced series of depressions in the channel's wall.
