Its ergonomic handle is crafted from black anodized T6 aluminum, ensuring a comfortable grip. Rest assured, 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 fantastic in your hand. For convenient carry, the TR-4 is equipped with a pocket clip on the back of the knife, allowing for easy and accessible transportation.
