Pro-Tech TR-5 Automatic Knife T503 – Black DLC CPM-S35VN Sterile Blade, Black Aluminum Handle, Push Button Auto, USA Made

The Pro-Tech TR-5 T503 is a no-nonsense, all-black automatic built for those who appreciate clean lines, hard-use performance, and understated tactical appeal. Featuring a sterile blade with no extra markings, this version keeps things minimal while delivering maximum capability.

At the push of a button, the TR-5 fires open with Pro-Tech’s renowned coil spring action—fast, decisive, and incredibly consistent. This is the kind of deployment you feel every time, with a solid lockup that inspires confidence.

The 3.25-inch CPM-S35VN blade is built for real-world performance, offering excellent edge retention, corrosion resistance, and toughness. Finished in a durable black DLC coating, the blade is highly wear-resistant while maintaining a low-profile, non-reflective look.

The black anodized 6061 aluminum handle keeps the knife lightweight and durable, with ergonomic shaping that locks naturally into the hand. A sliding safety switch adds peace of mind during carry, preventing unintended deployment when in your pocket.

Finished with a deep-carry clip for discreet everyday carry and a lanyard-ready backspacer, the TR-5 T503 is a purpose-driven automatic that balances performance, simplicity, and reliability. Proudly made in the USA, it’s built to be used—not just admired.
