The Microtech Ultratech OTF Blue Spartan D/E Stonewash Full Serrated (223-12BL) is a high-performance out-the-front automatic knife built for extreme cutting power and tactical reliability. As part of Microtech’s flagship Ultratech series, this model features a double-action OTF mechanism that delivers rapid, smooth blade deployment and retraction with proven durability.
Equipped with a Spartan double-edge (D/E) blade, this variant is designed for maximum penetration and aggressive cutting tasks. The full serrated edges on both sides dramatically enhance slicing efficiency, making it ideal for cutting through rope, webbing, and other tough materials. (D/E refers to a double-edge blade configuration, commonly paired with serrated or plain edge variations.)
The blade is crafted from premium M390 steel, offering superior edge retention, corrosion resistance, and long-term performance. A rugged stonewash finish helps hide wear and scratches, keeping the blade looking clean even after heavy use.
