The TR-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. This TR-4 features a 4" black DLC finished 154-CM 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. Also includes a black nylon sheath.

I've had this knife for about six months now and wanted to hold off on my review. This knife is amazing and is my primary duty knife. The blade is sharp, action is fast, and overall quality is outstanding. I also like the steel glass breaker which can also be used to attach a lanyard. It is a bit larger than most pocket knives, but it's not heavy and has a relatively slim profile for its size. This knife has been used & abused and is still just as sharp as it was on day one. Highly recommended!
