Semi -disconding blade

Semi -breaking divided into a blade blade belongs to a very precise tool，The cumulative tolerance of the outer diameter is 0.02mm (the human hair is normal at 0.08mm) is mainly used for two layers of materials at the bottom of the bottom.，At present, there are only two materials，SKH-51 and tungsten steel，The shortcomings of tungsten steel are high and crispy，It is easy to break the mouth when adjusting the knife，Therefore, the price of tungsten steel is slightly lower than SKH-51，But the high hardness brings it good abrasion resistance。
