Abstract
An improved thumbpiece for a power-driven knife is disclosed. The one piece thumbpiece includes an annular base portion and a thumb support portion disposed vertically above the base portion. The base portion is adapted to be mounted on an annular boss extending from the headpiece. The thumb supporting portion includes a thumb contacting surface which extends outwardly at an acute angle with respect to the longitudinal axis of the base portion. The thumb contacting surface is patterned and is generally sinusoidal in profile and convex in cross section for supporting an operator's thumb in a partially flexed position along substantially the entire length of the thumb.
