The ProTech T4105 F MM TR-4 (Tactical Response 4) is a premium American-made automatic knife engineered for demanding professional, tactical, and everyday applications. Built with ProTech’s renowned precision manufacturing, this full-size automatic combines rugged durability, dependable deployment, and modern premium materials into one highly capable cutting tool. The TR-4 has earned an outstanding reputation among military personnel, first responders, law enforcement professionals, and knife enthusiasts who require uncompromising performance in a dependable automatic platform. This configuration features a rugged black 6061 aircraft-grade aluminum handle with ProTech’s distinctive Feather texture pattern, providing enhanced grip without being overly aggressive in the hand. The ergonomic handle offers excellent control during extended use while maintaining a streamlined profile for comfortable carry. A steel secondary safety switch adds an additional layer of security by helping prevent unintended deployment when the knife is stored or carried. The 4.00-inch drop point blade is crafted from premium CPM MagnaMax stainless steel, one of the most advanced blade steels available today. MagnaMax delivers an exceptional combination of edge retention, toughness, and outstanding corrosion resistance, making it an outstanding choice for both hard-use environments and everyday carry. The stonewashed finish helps conceal normal wear from use while reducing glare and giving the blade a rugged working appearance. Deployment is instantaneous through ProTech’s powerful push-button automatic mechanism, which is widely recognized for its smooth, reliable action. The button lock securely holds the blade open during use, while the integrated glass breaker at the end of the handle provides valuable emergency utility. Completing the package is a black long deep-carry pocket clip that keeps the knife riding discreetly and securely in the pocket for convenient everyday carry. Proudly manufactured in the USA, the ProTech TR-4 T4105 F MM delivers premium materials, precision machining, and proven reliability for users who expect exceptional performance from every component.
