Microtech Ultratech Gen IV Spartan Black Topographic Deep Engraved Aluminum, Stonewashed Böhler M390MK by Tony Marfione (12234TP-10) is a premium-class OTF automatic knife, equipped with a double-edged Spartan blade, new Gen IV mechanics, and an aluminum handle featuring a deeply engraved topographic pattern. The design combines compact dimensions, fast blade deployment and retraction, and the distinctive styling characteristic of Microtech.
The D/A OTF mechanism is operated by a wide X-button slider, which extends and retracts the blade using the same control element. The milled platform beneath the slider reduces friction and helps minimize dirt buildup. A titanium clip with a ceramic ball, steel Torx screws, and an integrated steel glass breaker round out the model’s functional design.
Böhler M390MK – Powder Steel for Demanding Use
The blade is made of Böhler M390MK steel with a hardness of 61–62 HRC. The material combines high wear resistance, good corrosion resistance, and long-lasting sharpness. These properties prove useful when regularly cutting cardboard, tape, cord, plastics, and other everyday materials.
Spartan / Dagger, Double Edge, and Stonewashed
The Spartan / Dagger, Double Edge profile features a symmetrical tip and two functional cutting edges. The Flat grind ensures stable blade guidance, while the Stonewashed finish gives the blade a matte, utilitarian look and helps mask minor signs of wear.
Black Topographic Deep-Engraved Aluminum and Gen IV Mechanism
The handle is made of 6061-T6 aluminum. The topographic pattern is deeply engraved directly into the aluminum surface, so it is neither a print nor an applied layer. The widened Gen IV slide moves along a milled platform, and a titanium clip with a ceramic ball makes it easy to slide the knife into a pocket.

Frequently Asked Questions
How do I care for and sharpen Böhler M390MK steel?
After use, clean the blade and dry it thoroughly. Diamond stones, CBN systems, or precision guide systems work best for sharpening.
How does the D/A OTF mechanism work?
The D/A OTF mechanism extends and retracts the blade using the same slide. Pushing the slide forward automatically extends the blade, while pulling it backward retracts it into the handle.
What makes the Topographic Deep Engraved handle stand out?
The topographic pattern is deeply engraved directly into the surface of the aluminum handle. It is not a print or a separate layer, making it an integral part of the design.
What has changed in the Ultratech Gen IV generation?
Gen IV features a wider X-button slide operating on a milled platform, steel Torx screws, a milled titanium clip with a ceramic ball, and an upgraded OTF mechanism.
Does the knife have a glass breaker?
Yes. The steel glass breaker is an integral part of the design and expands the knife’s functionality in emergency situations.
