ABSTRACT:
An improved wedge of the multi-blade type, particularly adapted for hand-held use. Four tapered blades extend substantially 90.degree. apart, and a short driving head arises from their midst. A separable point extends from the root of the four blades. The leading edges of the blades are raked at an angle which provides optimum penetration and splitting characteristics, and allows the wedge to be easily manipulated for use as a hand-held tool. The flanks of the blades are generally concave so that the transverse thickness of the blades increases slightly over the lower half of the blade length, but very substantially over the upper half.
