The Microtech Ultratech OTF Blue Spartan D/E Black Full Serrated (223-3BL) is a bold, high-performance automatic knife built for extreme cutting tasks and tactical precision. As the flagship model in Microtech’s Ultratech lineup, it features a double-action out-the-front (OTF) mechanism engineered for fast, smooth deployment and retraction while minimizing internal wear through its advanced spring system.
This model is equipped with an aggressive Spartan double-edge (D/E) blade finished in a stealthy black coating, offering enhanced corrosion resistance and a tactical, low-profile appearance. The full serrated edges on both sides deliver exceptional cutting power, excelling at slicing through rope, webbing, and other tough materials with ease.
Crafted from premium M390 blade steel, the Ultratech provides outstanding edge retention, durability, and resistance to corrosion—making it ideal for demanding users and collectors alike. The blue anodized 6061-T6 aluminum handle adds a striking contrast while maintaining a lightweight, ergonomic grip for everyday carry or field use.
