ABSTRACT:
The thread snips include two metal blades connected together, adjacent their rounded, rear ends, so that their pointed, front ends may be moved or pivoted relative to each other, in planes generally parallel with the planes of the metal blades, between open and closed positions. The rearward portion of each metal blade has a reduced thickness. Plastic inserts are molded onto these rearward, reduced thickness portions so that the inner facing side surfaces of the plastic inserts define a smooth continuation of the inner facing side surfaces of the metal blades. The rearward ends of the plastic inserts are thicker than their forward ends. The increased thicknesses force the rear ends of the metal blades apart, and thus cause the blades, forward of the point of connection, to bend or arch.
