Flies shearknivesare specially heat treated for optimum toughness and abrasion resistance to make them highly resistant to damage, impact, vibration, clamping and cutting force. Files shear knives's lifeare above 3-5 times of the overall alloy tool steel bit , and may carry on the pre-protection and repair.
