The TR-4 knife from Pro-Tech is a fresh and innovative addition to their popular Tactical Response line. One of the most requested features, a sliding safety, has been incorporated into the front of the handle. This particular TR-4 model boasts a 4-inch black DLC finished blade made from incredibly durable CPM-D2 steel, featuring a plain edge. The handle is ergonomically designed and made from black anodized T6 aluminum. When it comes to performance, the TR-4 is a reliable companion that won't disappoint. It fires with impressive force, locks up securely like a rock (as expected from Pro-Tech), and feels great in your hand. For convenient carry, the TR-4 also includes a pocket clip on the back of the knife, allowing for easy and accessible transportation.
