Abstract:

A combination rasping/filing tool comprises an axially extending blade having first and second surfaces and proximal and distal ends. The first surface has a plurality of rasping teeth.

The raised portion has a trailing shoulder extending proximally away from and contiguous with a sharpened rasping ledge. A rasping face is contiguous with the rasping ledge and projects into the rasping cavity. Each rasping tooth is arranged in a row of a plurality of teeth, and each row is staggered in relation to proximally and distally neighboring rows. In one embodiment each row comprises eight teeth.
