Abstract
Abstract A claw having a sharp edged tip is disposed at the extremity of a handle supported shank. The configuration of the tip provides a cutting edge adapted for removing denture material in confined as well as open areas of a denture. The surfaces of the shank, including at least a side surface of the claw, are abrasive for grinding and smoothing surfaces of the denture.
