Description

  The present invention relates to a cutter knife manufacturing technical field, and more particularly, to a new blade portion fixed cutter knife.

  Ceramic is a wear-resistant material that is non-rusting and ecological. Therefore, when ceramic is used in the blade of a cutter knife, the sharpness of the cutting edge is difficult to drop. Ceramic blades have excellent wear resistance, but the disadvantage is that ceramic blades are very fragile, easy to break, break, and the larger the area, the higher the market price of the blades. The technical level is limited, and because there is very little ceramic material in the blades sold in the market, the technical performance of which superior performance is operated by improving and overcoming the disadvantages of ceramic blades There is an urgent need to find a means.

  Accordingly, the present invention aims to provide a new blade-fixed cutter knife with respect to the shortage of the prior art.
