Abstract: A two-piece shear knife replaces a conventional one-piece shear knife for use in a power shear. The two-piece knife includes a main body with a cutout formed by first and second inner surfaces. A blade insert with a single cutting edge is seated in the cutout. One of the inner surfaces of the cutout and the complementary abutting insert surface are angled toward a confronting surface to direct shearing forces from the cutting edge diagonally inwardly toward the inner corner of the cutout and into the main body. This efficiently transfers shearing forces and reinforces seating engagement of the insert. The two-piece construction of the shear knife allows the main body to be made from a less expensive, less wear resistant material.

Abstract: A golf swing training device (10) including a grip (12), an elastic cord loop (14), a neck pad (16) and an adjustment mechanism (18). Grip (12) is in the form of a conventional golf club grip. The elastic cord loop (14) is secured at the narrow end of grip (12). Adjustment mechanism (18) allows the length of cord loop (14) to be selectively adjusted for a particular golfer. Neck pad (16) includes straps (50), through which cord loop (14) is inserted. Neck pad (16) doubles as a carrying case for the grip and cord loop. Neck pad (16) includes a sleeve (66), closed at one end by a flap (60).
