Features: Drop point blade made of D2 steel with a black finish. Automatic push button opener with a slide lock. Texturized black handle with a lanyard hole. Titanium frame lock with steel lockbar insert. Reversible pocket clip set up for tip-down/tip-up carry. Description: 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 D2 steel blade with a plain edge. 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. Pro-Tech Knives are high quality and available in a variety of shapes and sizes. Check out what Blade HQ has to offer today!
