The Microtech UTX-85 Gen IV 12324-1OBDS is a compact OTF automatic knife from the Signature Series, featuring a double-edged Dagger blade made of Böhler M390MK steel. The distinctive Outbreak finish covers both the blade and the aluminum frame, and the deep engraving on the handle gives this variant a distinctly collectible and technical character.
The fourth generation of the UTX-85 retains the series’ compact form, with an overall length of 194.31 mm and a weight of 87.88 g. The OTF Double Action mechanism allows the blade to be automatically extended and retracted with a single slide, while the redesigned frame and controls improve the ergonomics of everyday use.
Böhler M390MK – high resistance to wear and corrosion
The blade is made of Böhler M390MK steel, which combines high abrasion resistance with very good corrosion resistance. In a compact OTF knife, this is particularly important because it helps maintain a sharp edge for a long time even with frequent use and reduces the surface’s susceptibility to moisture and the conditions of everyday carry.
Double Edge Dagger, flat grind, and Outbreak
The Double Edge Dagger profile features a symmetrical geometry with two cutting edges and a centrally aligned tip. The flat grind ensures smooth cutting on both sides of the blade, while the Outbreak finish gives the surface a distinctive, irregular appearance that complements the Signature Series’ design.
Outbreak Deep Engraved Aluminum and OTF Mechanism
The handle is made of 6061-T6 aluminum and finished in the Outbreak style with deep engraving. The body’s design also incorporates a rear section that serves as a backspacer, eliminating the need for a separate component in that area. The Double Action OTF mechanism is operated by a single slider, and the redesigned grip surfaces provide secure control over the compact body.

Frequently Asked Questions
What are the properties of Böhler M390MK?
M390MK offers high wear resistance and very good corrosion resistance. As a result, it maintains its cutting edge for a long time and performs well in a compact OTF knife designed for regular use.
How do you sharpen the Double Edge Dagger blade?
It’s best to sharpen each edge separately, maintaining as symmetrical a geometry as possible on both sides. Diamond abrasives or a guide system that helps maintain a consistent angle work well with M390MK.
How does the OTF Double Action work?
The same slider is responsible for automatically extending and retracting the blade. This allows the entire operation to be performed with one hand without manually folding the blade.
What do “Outbreak” and “Deep Engraved” mean?
“Outbreak” refers to a distinctive, irregular surface finish, while “Deep Engraved” refers to deep engraving on the body. The combination of these two elements gives the Signature Series a more striking, technical look.
How does the UTX-85 stand out from the Ultratech?
The UTX-85 retains the design and functionality typical of the Microtech OTF family but offers more compact dimensions. This makes it easier to carry while remaining a full-fledged Double Action automatic.
