Protech 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 Protech TR-5 Assist is legal to carry in most places.

This TR-5 model has a black anodized aluminum handle featuring a Shaw Sterling Skull. It has a two-tone black back spacer/lanyard attachment, and a deep carry tip-up pocket clip. The blade is black DLC finished and outfitted with a thumb stud opener. The plunge lock enables safe use and provides solid lockup. Protech's TR-5 is an impressive addition to their lineup and boasts their longstanding build-quality and performance.

This is a limited SHOT Show 2016 Run of 50 numbered knives.

Protech's Lerch is terrific. Blade shape and action are perfect. Light weight, well made, and perfect deep pocket clip. One of the collection that will make it into the EDC rotation tomorrow. I'm glad I sprung for the special edition. #46 of 50. Best spring assisted folder in my collection. Enjoy!
