Scraper knife for stripping silicon chip

A scraper knife for stripping a silicon chip comprises a knife handle and a knife body. The knife handle is connected with the knife body, the lower surface of the knife body is a belly surface in a cambered surface structure, the upper surface of the knife body is a back surface which is an inclined flat surface, the knife body is made of polyether-ether-ketone resin in an integral structure, and the knife handle is still made of PVC (polyvinyl chloride) materials and provided with mounting holes. As the knife body is made of the polyether-ether-ketone resin, abrasive resistance is greatly improved and the service life of the scraper knife is prolonged, and the belly surface is the cambered surface so that convenience in operation is effectively enhanced and sophisticated high-precision design is sufficiently achieved.
