The hand tool has a head with two pivotally joined halves including at least one pair of gripping jaws. The tool head preferably includes tips that may be used to dig beneath a fastener head that is flush with or set below a surface. The tool includes a pair of handles operable to close the gripping jaws. The handles are preferably offset above the plane of the tool head such that they operate as a lever in cooperation with a fulcrum on the bottom of the tool head to extract the fastener. In one embodiment, the forward jaws of the tool have concave curved gripping surfaces. In one embodiment, the rearward jaws have non-complementary surfaces.
