ABSTRACT:
A handle for the handpiece of a meat trimming knife is a one-piece tubular-shaped hollow member provided with a contour formed by three distinct annular sections. A center section has a concave cross-sectional configuration with one of the end sections having a cylindrical configuration and the other end section having a convex cross-sectional configuration. A series of circumferentially spaced longitudinally extending grooves are formed in the convex end section. The grooves are generally truncated V-shaped in cross section. The bore within the cylindrical end section is flared outwardly providing a gradually curved smooth surface engaged by a flexible drive cable to reduce fatigue on the cable as it extends into the bore of the handle for rotatably driving a ring knife mounted on a blade holder attached to the convex end of the tubular member by an annular coupler. The coupler is grooved similar to the convex section of the handle and has an annular collar attached to the front end which is formed with an outwardly flared flange which protects the fingers of an operator. The shape of the handle reduces the gripping force heretofore required to prevent slipping of the handpiece in an operator's hand thereby reducing fatigue on the operator's hand.
