The Tactical Response 4 is a whole new take on Protech's popular Tactical Response line. It incorporates a much requested sliding safety (on the front of the handle). The TR-4 features a 4" bead blasted 154-CM blade (serrated). The ergonomic handle is black anodized T-6 6061. 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 feel great. The TR-4 has a pocket clip (tip up) on the back of the knife for easy carry. Also includes a black nylon sheath.
