This TR-4 features a 4" stonewashed blade with a plain edge and a feather grip textured handle. The TR-4 is a whole new take on Pro-Tech's popular Tactical Response line. It incorporates a much requested sliding safety on the front of the handle. The ergonomic handle is black anodized T6 aluminum with a grippy "Feather" texture. The TR-4 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. The TR-4 has a pocket clip (tip up) on the back of the knife for easy carry.
