Pro-Tech TR-5 operator series. Automatic knife with a sterile S35-VN blade. Knife has a tritium push button with lock and is in great condition, I would say almost new. I bought this knife on an impulse because I’m a sucker for blacked out knives. Knife has had some light use-meaning it opened a few Amazon packages. You can see some slight marks near the tip of the blade from use. Knife is razor sharp and has that great Pro-Tech action. Comes with original box and draw string pouch.
