Abstract
A knife for drawing along a cutting channel in a template defining a puzzle piece outline, so as to cut an underlying workpiece along lines conforming to the shape of the puzzle piece outline to form a puzzle piece from the workpiece. The knife includes a handle portion, a hollow nose portion mounted on the handle portion, a blade mounting portion contained by the nose portion and rotatable therein and extending distally therefrom, and a cutting blade mounted on the blade mounting portion and extending distally therefrom. The cutting blade includes a leading edge, a longer trailing edge, and a cutting edge extending therebetween. In its preferred form the knife includes a shield that is disposed forwardly of the leading edge of the cutting blade and extends along at least a portion of the length of the leading edge of that blade. The cutting blade and shield are dimensioned to enter and move along the cutting channel of a template, with the cutting edge engaging the workpiece for the forming of the puzzle piece and the shield coacting with the sides of the channel to prevent the cutting edge from cutting into the template.
