PROBLEM TO BE SOLVED: To increase vibration-damping properties and to improve negative conditions relating to shock absorptivity, pressure dispersion, weatherability, and other operation environment assessment from many sides by adopting compound covering using two or more soft elastic materials for a grip covering of a scissors type manual gadget.SOLUTION: In a scissors type manual gadget X, the respective grip bodies 12(1) of scissor elements 1 are covered with a cover bodies 2(10) made of a plurality of soft elastic materials. Moreover, on the respective inner surfaces of the free ends of the grip bodies 12(1), buffering members 3(10) made of the plurality of soft elastic materials are each provided and oppose each other so as to be able to abut elastically in cutting operation. Both of the cover bodies 2(10) and the buffering members 3(10) are obtained by laminating two or more kinds of soft elastic materials having different physical properties to compositely form inner and outer layers. Both constitution materials of respective innermost layers are vibration-damping rubber 21;31 having a shock absorption ratio of 80% or more, and both constitution materials of respective outermost layers are silicon resin 22;32. |
