Microtech DOC Killswitch Automatic Knife Partially Serrated Satin S/E Black AUMT1545

Built for serious performance and unmistakable tactical style, the Microtech DOC Killswitch delivers the rugged capability expected from a collaboration between two legendary knife designers. This out-the-side automatic deploys instantly with a push of the button, launching the blade into action and locking it firmly in place. The action is crisp and authoritative, giving you fast, reliable deployment whenever the moment calls for it.

The 3.75" drop point blade is crafted from premium steel and finished in a clean satin finish that highlights the blade’s precision grind while offering a classic, hard-working look. A partially serrated edge provides outstanding versatility, combining the smooth slicing control of a plain edge with the aggressive cutting power of serrations. It tears through rope, webbing, and other tough materials while still delivering precise cutting performance for everyday tasks. The drop point profile adds excellent tip strength and control, making it a dependable blade shape for a wide range of cutting situations.

The DOC, short for Death on Contact, is the result of a collaboration between Anthony Marfione and Mick Strider—two names known for designing hard-use knives with bold, unmistakable character. This automatic version carries the name Killswitch, inspired by its distinctive fire-safe selector built into the knife. Much like a rifle safety, the switch flips between white for safe and red for fire, giving the knife both visual impact and functional control.

The handle is machined from textured black aircraft-grade aluminum, providing exceptional durability while ensuring a secure grip in demanding conditions. The aggressive texture helps keep the knife planted in your hand during use, and a built-in lanyard hole offers another practical carry option. At 5.25" closed and weighing 6.8 ounces, the DOC Killswitch has a substantial, confidence-inspiring feel while remaining practical for everyday carry.

Proudly made in the USA, this knife reflects Microtech’s commitment to precision manufacturing, premium materials, and uncompromising craftsmanship.
