A covers anti-etching protective layer in the two sides before and after metal sheet;

B. leave corresponding etching window at the protective layer on metallic plate two sides according to required knife-edge, the etching window of metallic plate rear surface misplaces with the etching window of front surface, guarantees that promptly the rear surface etching window widens in cutter root one side than front surface etching window;

C. the etching liquid with energy etching metal impacts metallic plate at the rear hatch place, and the etching liquid of Liu Donging soaks into front window under pressure-less state at random, and the metal that is exposed to etching window is etched, and forms the shape of cutter;

D. place to go protective layer, the clean metal plate;

E. with mould to the metallic plate punching press, make the outstanding metallic plate face of blade of the cutter that forms through etching.

Preparation method of scraping sharpener of the present invention, because etching window dislocation in the metallic plate both sides, and rear hatch is big than front window in heel one side, in etching procedure, etching liquid under stress impacts the metal that is exposed to rear hatch, make the rear surface obtain etching quickly, and front surface is soaked into by stress-free etching liquid and etching more slowly, after the etching, form a sharp blade at cross section metal near the front surface place, and blade to front surface has an inclination angle, and the silk of being convenient to cut, sheet separate with body.In addition,, make that blade cutter base is long and form a cambered surface, cut more smooth and easy along cutting discharging direction because the front and back etching window misplaces.Use the sharpener of scraping of manufacturing of the present invention, its knife edge is sharp, and scraping is laborsaving and smooth, can make to be cut thing and to be cut into shape intact silk or sheet continuously.
