Microtech DOC Killswitch Automatic Knife Serrated Blackout S/E AUMT1541T

Built with serious attitude and uncompromising performance, the Microtech DOC Killswitch stands out as a powerful automatic born from the collaboration between two legendary knife designers. This out-the-side automatic deploys instantly with the push of a button, sending the blade snapping open and locking it firmly in place. The action is fast, decisive, and engineered for reliability when quick deployment matters.

The 3.75" drop point blade is crafted from premium steel and finished in a durable black coating that adds corrosion resistance while giving the knife a stealthy, tactical appearance. A fully serrated edge delivers aggressive cutting power, tearing through rope, webbing, heavy cordage, and other tough materials with ease. Combined with the drop point profile’s excellent tip strength and control, this blade is built for demanding cutting tasks where raw cutting performance is essential.

The DOC—short for Death on Contact—was developed through a collaboration between Anthony Marfione and Mick Strider, two names well known for designing hard-use knives with unmistakable style. This automatic variant is called the Killswitch, a name inspired by its distinctive fire-safe selector built into the design. Much like a rifle safety, the switch flips between white for safe and red for fire, adding a bold visual element while giving the user clear control over the knife’s readiness.

Textured black aircraft-grade aluminum handles provide the strength needed for a knife of this caliber while maintaining a secure grip in demanding conditions. The aggressive texturing helps keep the knife planted in your hand, even during hard use. A built-in lanyard hole adds another practical carry option. Measuring 5.25" closed and weighing 6.8 ounces, the DOC Killswitch carries with a solid, confidence-inspiring feel.

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