Abstract:
1. A process of manufacturing a pair of surgical scissors having a pair of blades connected at a pivot, each of the blades having a length, a tip portion, a body portion, an outer surface, an inner surface and a cutting edge, the cutting edge forming an angle with the outer surface along the length of the blade, comprising the steps of: heat treating a block of material to form a pre-hardened block of material having a desired hardness; applying an electrical discharge machining process to the pre-hardened block of material to accurately form the blades into a desired blade profile comprising the inner surface and the outer surface of the blade from the pre-hardened block of material; refraining from additional heat treating of the blades having the desired blade profile formed by the electrical discharge machining process; and sharpening the cutting edges of the blades.
