Pro-Tech TR-5 Tactical Response 5 Operator Edition T503-Operator — 3.25″ Sterile DLC Black CPM-S35VN, Black Aluminum, Tritium Push Button

The Pro-Tech TR-5 Operator Edition T503-Operator is a fully sterile push-button automatic built for those who need a deployable knife that carries no identifiers. No Pro-Tech logo. No blade etch. No markings anywhere on the knife or hardware.

The 3.25-inch CPM-S35VN drop point blade wears a matte DLC black finish that eliminates both glare and reflection. At 0.125 inches thick with a plain edge, it’s built for clean, purposeful cutting — not showmanship. The machined black aluminum handle runs 4.375 inches closed and 7.625 inches overall, with all hardware finished in matching black DLC. The deep-carry tip-up pocket clip disappears in the pocket.

The single break from the sterile-black build is deliberate: a tritium push button. The self-illuminating tritium vial requires no batteries, no activation, and no ambient light. It glows continuously for years, letting the operator locate and deploy the knife in complete darkness without breaking light discipline. A slide safety locks out the button for secure carry.

The TR-5 platform has been one of Pro-Tech’s workhorses since its introduction — a larger-format automatic with a refined single-action mechanism that locks up fast and firm. This Operator Edition takes the same proven platform and removes every feature that isn’t functional. Built in Placentia, California by Pro-Tech Knives.
