Microtech Ultratech 121-4BL, the gold standard in out-the-front (OTF) knives. As the original dual-action OTF offering from Microtech, the Ultratech serves as the foundation for their entire line of OTF knives. Over the years, it has undergone numerous modifications, consistently improving its efficiency and reliability. This particular model boasts an enhanced contoured handle and a textured thumb slide for a secure grip and effortless handling.

The Ultratech’s unique spring design remains in an “at rest” position, except when the knife is deployed. This innovative feature ensures that the compressed spring avoids fatigue, providing users with confidence that the knife will operate effectively when fired. The Ultratech is highly customizable, with options for a standard machined aluminum top or a carbon fiber piece. Its lightweight construction, one-handed open and close action, slim profile, and scalpel-sharp blade make it an unparalleled offering, exclusively available through Microtech. The Ultratech has demonstrated its ability to overcome any obstacle time and time again, with future developments eagerly anticipated.
