ABSTRACT:
A shears includes a pair of blade portions with opposed convexly curvilinear cutting edges extending longitudinally thereof assembled for pivotal movement between closed and open positions. The curves defined by the cutting edges are mirror images and, in the open position, intersect at a point spaced from the pivot means towards the outer end of the cutting edges. The cutting angle defined by tangents to the curves at the points of intersection over substantially the entire length of the cutting edges during closing movement is substantially constant and within the range of 12.degree.-30.degree.. The preferred shears have a rake angle of 4.degree.-14.degree. and have blade portions which are inclined towards each other to provide wiping action at the point of intersection along substantially the entire length of the cutting edges.
