ABSTRACT:
A hand tool is disclosed for extracting a fastener from a material. The hand tool includes a pair of elongate members joined by a pivot to form a pair of jaws and a pair of handles. The pair of jaws are operated by moving the pair of handles relative to one another, and have teeth adapted for gripping a portion of the fastener. Each of the elongate members is curved longitudinally in a plane including an axis of the pivot such that when the fastener is gripped in the pair of jaws, a force applied to the handles tends to extract the fastener from the material while minimizing damage to the material.
