The Tactical Response 3 features a DLC 154-CM blade (partially serrated) and a black anodized T-6 6061 body with machined grooves. The TR-3 is a knife that will not let you down. It fires hard, locks up like a rock (what else would you expect from Pro-Tech?) and feels great in your hand. The slim design rides well in the pocket (black pocket clip is on the back of the knife).
