Microtech UTX-85 Gen IV Spartan Black Topographic Deep Engraved Aluminum, Apocalyptic Böhler M390MK by Tony Marfione (12304TP-10AP) is a premium OTF automatic knife, equipped with a double-beveled Spartan blade, a Gen IV mechanism, and an aluminum handle featuring a deeply engraved topographic pattern. The model is approximately 85% the size of the full-size Ultratech, offering a more compact form suitable for everyday carry.
The D/A OTF mechanism extends and retracts the blade using the same slider. The upgraded Gen IV drive system, milled platform beneath the slide, and crud cutter design ensure smooth operation and minimize the impact of fine debris. A titanium clip with a ceramic ball, steel Torx screws, and an integrated steel glass breaker round out the knife’s functional design.
Böhler M390MK – powder steel with high wear resistance
The blade is made of Böhler M390MK steel with a hardness of 61–62 HRC. The material ensures high abrasion resistance, good corrosion resistance, and long-lasting sharpness. It performs well when cutting cardboard, tape, cord, plastics, and other everyday materials.
Spartan / Dagger, Double Edge, and Apocalyptic
The Spartan / Dagger, Double Edge profile features a symmetrically shaped tip and two functional cutting edges. The Flat grind supports stable blade control, while the Apocalyptic finish gives the blade a rugged, weathered look and helps mask minor signs of regular use.
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; it is not a print or an applied layer. The rounded profile of the handle and the side grooves provide a secure grip, while the wide Gen IV slide facilitates smooth operation of the automatic mechanism.

Frequently Asked Questions
How do I care for and sharpen Böhler M390MK steel?
After use, clean the blade and dry it thoroughly. For sharpening, it is best to use diamond stones, CBN systems, or a precision guide system, as M390MK is highly resistant to abrasion.
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 moving it in the opposite direction retracts it into the Handle.
What has changed in the UTX-85 Gen IV generation?
Gen IV features an upgraded drive system, a wider slide operating on a milled platform, and a crud cutter design that helps minimize the impact of fine debris on the mechanism’s operation.
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.
Does the knife have a glass breaker?
Yes. The steel glass breaker is an integral part of the design and enhances the knife’s functionality in emergency situations.
