Pro-Tech Knives T4103 MM OP Auto Tactical Response 4 Operator Series DLC Sterile MagnaMax Saber Grind Blade with Black Handle / Tritium Button / Black Hardware and Clip

The Pro-Tech T4103 MM-OP Tactical Response 4 Operator takes the full-size TR-4 platform and gives it the stripped-down, blacked-out treatment of Pro-Tech's Operator Series. This configuration pairs a sterile DLC-coated MagnaMax blade with a black aluminum handle, tritium firing button, and matching black hardware and pocket clip.

The 4-inch MagnaMax blade uses a saber grind that leaves substantial material through the spine while maintaining practical cutting geometry for demanding utility work. The sterile DLC finish removes external blade markings for a cleaner appearance while adding a durable, low-reflective surface treatment.

The black 6061-T6 aluminum handle retains the deep finger grooves and sculpted profile that define the Tactical Response 4, providing a secure full-size grip without unnecessary bulk. A tritium-inlaid firing button remains visible in low light and serves as the defining detail of Pro-Tech's Operator treatment, while black hardware and a matching black pocket clip complete the subdued finish package.

Pro-Tech's push-button automatic mechanism delivers the fast, authoritative deployment associated with the Tactical Response series, while the secondary safety allows the action to be locked when desired. At 9.25 inches overall, the TR-4 Operator remains a substantial American-made automatic built around secure handling, straightforward operation, and a deliberately low-profile appearance.
