| 摘要 | PURPOSE: To manufacture scissors of high sharpness and low cost, by pressing a cutting blade material to provide a recess of prescribed depth inside the periphery of the material and by injection-molding a synthetic resin on the surface of the cutting blade material and in the recess. CONSTITUTION: A cutting blade material 1 is provided with a recess 3 inside the periphery 2, a supporting through hole 4 and coupling holes 5 by pressing or the like. The cutting blade material 1 is set in a mold for injection molding. A synthetic resin is poured into the mold to form a handle part 19 and a cutting part 18. Since the synthetic resin is filled in the recess 3 and the through holes 5, the synthetic resin is firmly bonded with the cutting blade material 1. COPYRIGHT: (C)1980,JPO&Japio |
