ABSTRACT:
A tool for applying compression, most suitable as an edible nutshell remover, comprises a pair of elongated legs (10,12) hingedly attached at one end (14), with roughened jaw sections (30,34) adjacent the hinge and grasping sections (32,36) remote from the hinge. The legs are shaped such that when they are closed as far as possible the jaw opening diverges so that a nut or other workpiece can be placed at a location whereby maximum closure of the legs will crack the nutshell (42) without damaging the nutmeat (44). Also the jaw sections are curved in a matching convex-concave configuration so that when the legs are closed, the jaw sections will exert a combination of compression and rolling or shear forces upon the workpiece placed therebetween, so as to enhance the effect of the compressive force applied to the workpiece.
