Pro-Tech Knives is proud to be the first choice of Police and Military professionals around the world. Pro-Tech Knives are built to serve and serve well. This tactical manual folding knife by Pro-Tech Knives features a 4" 154CM stainless steel blade which is black DLC coated for tactical and corrosion resistance purposes. The blade jumps out of the handle with a push of the button and locks up with a very positive thwack. The anodized aluminum handle has excellently designed finger grooves for a variety of hand sizes and a backup safety switch which only locks the blade in the closed position. This knife is a great tactical deployment option that comes with a ballistic nylon sheath which is superbly made and easily attaches to LBE or any MOLLE system.
