This TR-5 model has a black anodized aluminum handle featuring a Shaw Sterling Skull with a mother of pearl button and a damascus blade. It has a two-tone back spacer/lanyard attachment, and a deep carry tip-up pocket clip.

Pro-Tech has added a spring assisted model to their Tactical Response lineup, the TR-5. Similar in design to the TR-4 auto, the TR-5 is smaller and more pocket-friendly. The assisted opening mechanism was developed by custom knifemaker and designer Matthew Lerch. Unlike most spring assisted knives, the TR-5 offers almost instant Assist engagement that is powerful. Sufficient force is required to activate the mechanism, providing an added measure of safety. Best of all, the Pro-Tech TR-5 Assist is legal to carry in most places. The plunge lock enables safe use and provides solid lockup. Pro-Tech’s TR-5 is an impressive addition to their lineup and boasts their longstanding build-quality and performance.
