About the ProTech TR-4.3 Tactical Response 4 Automatic Knife (4″ Black D2)

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. This TR-4 features a 4″ black DLC finished super tough CPM-D2 steel blade with a plain edge. The ergonomic handle is black anodized T6 aluminum. 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.
