Built with unmistakable attitude and serious cutting performance, the Microtech DOC Killswitch brings together two legendary design philosophies in one powerful automatic knife. This out-the-side automatic deploys with authority using a push button that both fires the blade open and locks it solidly in place. The action is fast, dependable, and engineered for those who expect instant response and uncompromising strength from their gear.
The 3.75" drop point blade is crafted from premium steel and finished with a durable black coating that enhances corrosion resistance while giving the knife a stealthy, tactical look. Its partially serrated edge provides the versatility to tackle a wide range of cutting tasks. The plain edge section delivers clean slicing performance, while the serrations bite aggressively through rope, webbing, and other tough materials. The drop point design adds excellent tip control and strength, making it a reliable performer whether it’s riding in your pocket for everyday carry or serving as part of a hard-use kit.
The DOC, short for Death on Contact, was developed through a collaboration between Anthony Marfione and Mick Strider, two names known for building knives that are as rugged as they are distinctive. This automatic version is called the Killswitch, named after its unique fire-safe selector integrated into the design. Much like a rifle safety, the switch flips between white for safe and red for fire, adding both visual impact and functional control to the knife’s deployment system.
Textured black aircraft-grade aluminum handles provide strength without unnecessary weight, while the aggressive texture helps ensure a confident grip in demanding conditions. The handle also includes a lanyard hole for additional carry options. Measuring 5.25" closed and weighing 6.8 ounces, the DOC Killswitch balances substantial build quality with practical everyday carry dimensions.
Proudly made in the USA, this knife reflects Microtech’s commitment to precision machining, premium materials, and uncompromising craftsmanship.
