高速鋼三面切書刀片系列Three - sided book  blade

三面切書刀需要門刀和側刀都具有高效率和整潔的裁切效果以及更長的使用壽命，我們獨特的刀鋒面幾何設計能夠改善裁切過程中刀片擠壓書本的情況，具有非常好的鋒利度，直線度和平直度，刀口鋒利，經久耐用。

The three-sided book cutting knife requires both the door knife and the side knife to have a fast and clean cutting effect and a longer service life. Our unique geometric design of the blade surface can effectively improve the situation that the blade squeezes the book during the cutting process
