Microtech DOC Killswitch Automatic Knife Partially Serrated Apocalyptic S/E Black AUMT15411AP

The Microtech DOC Killswitch is a commanding automatic knife built from one of the most recognizable collaborations in modern knife design. Developed by Anthony Marfione and Mick Strider, the Death on Contact platform combines aggressive styling with uncompromising strength. This automatic version earns the name “Killswitch” from its distinctive safety system, modeled after a rifle’s fire control selector that flips between safe and ready positions.

A 3.75" premium steel drop point blade delivers serious cutting power and added versatility with a partially serrated edge. The plain section provides controlled slicing and precision cuts, while the serrations bite aggressively into tough materials like rope, webbing, and heavy cordage. Finished in Microtech’s signature Apocalyptic treatment, the blade carries a battle-worn look that helps conceal wear while enhancing its rugged character.

Deployment is fast and authoritative thanks to the out-the-side automatic action. A push button fires the blade open instantly and locks it firmly into place once deployed. The Killswitch safety provides additional security by preventing accidental activation, giving the knife a familiar, intuitive feel similar to a rifle’s selector switch.

The handle is crafted from textured black aircraft-grade aluminum, delivering excellent durability without unnecessary weight. Precision machining adds grip and control, ensuring the knife remains secure in hand even during demanding tasks. The broad handle design fills the palm comfortably, while a lanyard hole at the base offers additional carry or retention options.

At 5.25" closed and weighing 6.8 ounces, the DOC Killswitch offers substantial presence while remaining practical for everyday carry. Its bold profile, powerful automatic action, and field-ready construction reflect the uncompromising design philosophy behind the Marfione and Strider collaboration.
