ABSTRACT:
A rasp tool comprises a handle and a cutter. The rasp tool carries a releasable locking assembly to couple the cutter to the handle. The releasable locking assembly is compactly arranged at the distal end of the handle and the mating proximal end of the cutter. The assembly includes a first interconnecting means for opposing longitudinal separation between the handle and the cutter, and a second interconnecting means for opposing lateral motion between the cutter and the handle. The releasable locking assembly provides an effective, simple to use, manually controllable means for attaching and detaching the cutter to the handle.
