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" stonewash 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.

Super job Bladehq: ordered the knife on late Thursday afternoon, in hand on Monday!!

This TR-4 more than exceeded my expectations.
Fires fast and locks-up every time it is operated.
Pro Tech is a premier manufacturer.
Second Protech!

Just got this tr-4 today. Already have a tr-3 that is outstanding. Anyway, this tr-4 is incredible. Fit and finish, blade centering, even grinds are all perfect. Also, no blade play in any direction!! Another home run for Protech and BladeHQ. P.S. Got the knife in 3 days!!!! Great job Bhq!
