The TR-2.3 has a black finished 154-CM spear point blade with a plain edge. Black anodized 6061-T6 aluminum body with black finished hardware. The Tactical Response 2 is a knife that won't let you down. It fires hard, locks up like a rock and feels great in your hand, but what else would you expect from Pro-Tech? The slim design fits well in the pocket and the knife features a convenient clip for carry.
