Built for hard use and unmistakable presence, the Microtech DOC Killswitch combines aggressive styling with the dependable performance expected from a collaboration between two legendary knife designers. This out-the-side automatic fires open with authority using a push button that both deploys the blade and locks it firmly in place. The action is crisp, powerful, and built for those who demand immediate readiness from their everyday carry.
The 3.75" drop point blade is crafted from premium steel and finished in a rugged stonewash that helps conceal wear while giving the knife a tough, work-ready appearance. Its partially serrated edge delivers outstanding versatility, pairing the clean slicing ability of a plain edge with the aggressive bite needed to tear through rope, webbing, and other tough materials. The drop point profile provides excellent tip strength and control, making it a reliable blade shape for both detailed work and demanding cutting tasks.
The DOC—short for Death on Contact—was created through a collaboration between Anthony Marfione and Mick Strider, two names known for designing knives built to handle serious use. This automatic version is known as the Killswitch, named for the distinctive fire-safe selector incorporated into the design. Much like a rifle safety, the switch flips between white for safe and red for fire, adding both visual character and functional control to the knife’s deployment system.
Textured black aircraft-grade aluminum handles provide exceptional durability while maintaining a secure grip in demanding conditions. The aggressive texture helps keep the knife firmly planted in your hand, and the integrated lanyard hole offers an additional carry option when needed. At 5.25" closed and weighing 6.8 ounces, the DOC Killswitch delivers a substantial, confidence-inspiring feel while remaining practical for everyday carry.
