Cold Steel has been making push knifes for a quarter century. In those twenty five years we have continually been refining our designs, discarding features that didn't performa as well as we would have liked and enhancing those that did. These blades, and the wealth of experience that has gone into their manufacture, have paid off handsomely for Cold Steel as they have generated quite a following among law enforcement and military personnel around the world. This is because they offer "big knife" cutting and piercing potential in a very compact, easily portable size, and, unlike a revolver or semi automatic pistol, they never break, malfunction, or run out of ammunition. Designed by Lynn C. Thompson, our Safe Maker push knifes are, without doubt, the finest commercially made push knives in the world. The blade, shaft, and T shaped tang are all drop forged from one piece of AUS 8A stainless steel. This process, though costly, eliminates any unwanted sharp edges or surfaces that would irritate the hand or fingers when the knife is clasped in a closed fist, and it produces a better knife, since the subsequent vacuum heat treatment and sub zero quench, renders the blades virtually unbreakable. Well made blades deserve equally well-made grips. A lot of time and energy went into the production of our 'T' shaped handles. Made of shock absorbing Kraton they totally encapsulate the tang and part of the shaft so they can be comfortably and sercurely grasped in the fist with the blade jutting out between the fingers and used to deliver absolutely devastating punching and slashing blows. The Safe Maker knives includes an easily concealable and sturdy Secure-Ex boot/belt sheath.
