Milwaukee Tool Corporation's Fastback Knives, Nos. 48-22-1985, 1990 and 1995, feature one handed blade opening for easy activation. The Hawk Bill and Smooth Pocket Knife come designed to activate the blade three times faster than a two-handed opening with a press and flip opening. The Spring Assisted Knife delivers even faster activation by flipping open with the aid of a durable spring. Each of the knives feature a stainless steel blade with a sharp cutting edge that the user can re-sharpen. All Fastback knives also feature a thin body design and a wire form clip for comfortable pocket storage and quick access.
