1:The material of Blade;  The material  of  blade  is  SK5 steel,after extemely heat treatment craftwork,HRC riqidity achieve 58-60

 2: The surface of blade: The surface of blade plate hard chrome,in order to not easy rustiness, thereby extend the life of blade.

 3: The  knife-edge: The  knife-edge  come by especially  grind  craftwork, grind time  after  time ,the  surface will be more sleek so that mitigate the

4:cutting resistance,improve the effect of  cutting.

 5: The hohlschleifeng:  The especial craftwork of hohlschleifeng, reduce the  friction surace of blade,effective to mitigate the friction resistance.

  6:The  R edae  rounding:The especial  desian of R  edae rounding ,improve the effect of cutting ,and also extend the life of blade.

  7:The 45"  bevel cutting  edge:The design of 45" bevel cutting  edge, by  grind  time  after  time with  tartness blade ,achieve the best cutting effection.

 8: The shock mitigation systm: Equip the shock absorber  to  allevite  the  wallop  when completed cut,then protect the hand and wrist.

  9: Corner Angle arrow head:The design  of tiltede, allay the hurt of muscle  and  bones,and used much more comfortable.
