Microtech DOC Killswitch Automatic Knife Bead Blasted S/E Black AUMT1547

Built for serious performance with a bold tactical profile, the Microtech DOC Killswitch delivers the power and precision expected from a collaboration between two of the knife world’s most respected designers. This out-the-side automatic deploys instantly with a push of the button, sending the blade into action and locking it firmly in place. The mechanism is crisp, reliable, and built to perform when speed matters.

The 3.75" drop point blade is crafted from premium steel and finished in a rugged bead blasted treatment that cuts glare while giving the knife a clean, utilitarian appearance. Its plain cutting edge offers maximum slicing efficiency and easy maintenance, making it ideal for everyday cutting tasks as well as heavier utility work. The drop point profile provides excellent tip strength and controlled cutting performance, a shape trusted by professionals and knife enthusiasts alike.

The DOC, short for Death on Contact, is the result of a collaboration between Anthony Marfione and Mick Strider—two designers known for creating hard-use knives with unmistakable style. This automatic version is dubbed the Killswitch, named for the distinctive fire-safe selector integrated into the design. Much like a rifle safety, it flips between white for safe and red for fire, adding both visual character and functional control to the knife’s deployment system.

The handle is constructed from textured black aircraft-grade aluminum, offering outstanding durability while keeping the grip secure in demanding conditions. The aggressive texturing helps maintain control even during hard use, and the integrated lanyard hole provides additional carry options. Measuring 5.25" closed and weighing 6.8 ounces, the DOC Killswitch carries with authority while remaining practical for everyday use.

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