The Microtech Dirac Delta Tactical AUTO OTF Knife (227-1T) is a robust double-action out-the-front (OTF) knife designed for tactical and everyday carry. Its 3.79-inch double-edge dagger blade, crafted from Bohler M390 stainless steel with a black finish, provides exceptional sharpness and durability. The blade deploys smoothly via a face-mounted thumb slide, offering ergonomic operation distinct from spine-mounted designs, enhanced by Microtech’s ultra-high tolerance engineering.

★★★★★Weston S."Fantastic shop! Very helpful and has a good variety of Knives, Axes, and Accessories. They were able to reshape one my old knives that I’ve had for about ten years. The tip broke off a couple years ago by another person that used it. Now the knife looks like it had never happened. Definitely will be back for a new fixed blade when it gets closer to hunting season!"
