The Pro-Tech TR-5 Automatic Knife T503-OPERATOR is a premium tactical automatic knife built for performance, durability, and low-light functionality. As part of Pro-Tech’s renowned “Operator” series, this model features an all-blacked-out design paired with a tritium inlaid push button, making it both visually striking and highly practical in any environment.

Equipped with a 3.25-inch CPM S35VN blade, this knife delivers excellent edge retention, corrosion resistance, and toughness. The black DLC-coated finish enhances wear resistance while providing a stealthy, non-reflective appearance. Its drop point blade profile offers a strong tip and versatile cutting performance, making it ideal for everyday carry, tactical use, and utility tasks.

The handle is constructed from black anodized aluminum, offering a lightweight yet durable build. Its ergonomic design ensures a secure and comfortable grip, while the slim profile makes it easy to carry throughout the day. The standout feature is the tritium button, which glows in low-light conditions without requiring external charging, providing quick and easy access in the dark.
