The Microtech Ultratech Spartan Gen IV Topographic 12234TP-10 is a double-edged dual-action OTF automatic built around one of the most visually distinctive handle treatments in the current Microtech lineup — a topographic pattern deep laser engraved into black 6061-T6 aluminum that reads as sculptural rather than decorative. ⚠️ OTF automatic with dual sharpened edges — verify legal status in your jurisdiction before purchasing. Visit akti.org for knife law information.

The blade is Böhler M390MK — Microtech's in-house processed variant of Böhler M390, hardened to 61-62 HRC, delivering edge retention that far outlasts most production OTF steels while maintaining corrosion resistance for daily carry. The Spartan Dagger profile runs dual standard plain edges on a flat grind — both edges fully sharpened — giving this blade a 3.20" cutting edge that performs as a genuine two-edge working knife at 0.125" thick. The stonewash finish carries and wears well. ⚠️ Double-edged blade — verify local law separately before purchasing.

The Gen IV platform brings Microtech's patented Wide X-Button thumb slider — wider, more positive actuation than earlier generations — and a machined titanium pocket clip with ceramic ball retention. At 0.47" thick and 3.61 oz, this carries in a front pocket without bulk. Designed by Tony Marfione. Made in the USA.
