ABSTRACT:
A rasp handle has an elongate body portion with a pistol-type grip extending therefrom and rasp retaining structure at its front end. Such structure includes a fixed jaw and a slide jaw constructed and arranged for sliding movement relative to the fixed jaw between a forward closed locking position where a rasp is locked between the jaws and a rearward open rasp receiving and releasing position. A lever is connected to shift the slide jaw between its closed and open positions. A pivot interconnects the lever and the slide jaw so that the lever is free to move between a locked position adjacent the body portion and an unlocked jaw manipulating position away from the body portion.
