ABSTRACT OF THE DISCLOSURE A hedge trimming tool having a fixed elongated blade mounted to the power head of the tool and a cutting blade mounted over the fixed blade and reciprocating relative to the fixed blade in the direction of the lengthwise axis. A leading side of the fixed blade has projecting fingers or teeth and the overlying portion of the cutting blade has projecting teeth that reciprocate across the openings between the fingers. The reciprocating teeth have sides configured in a complex curve forming an hour glass planar profile and an inverted U-shaped cross section. The U-shaped cross section is provided by curving the sides of the teeth downwardly whereby the teeth sides are angularly projected through the plane defined by the bottom surface of the blade. The cutting edges along the sides are formed by grinding faces through the portions of the teeth projected below the bottom surface of the blade. The faces are formed in a single pass of the grinding implement with the faces parallel to the bottom surface of the blade.
