Microtech Ultratech Gen IV S/E Signature Cerakote Sand Trooper Aluminum, Cerakote Sand Trooper M390MK by Tony Marfione (11214-1SAD) – OTF Signature Series automatic knife

The Microtech Ultratech Gen IV S/E Signature Cerakote Sand Trooper Aluminum, Cerakote Sand Trooper M390MK by Tony Marfione (11214-1SAD) is a full-size OTF automatic knife featuring the D/A system, part of the Signature Series. The fourth generation of the Ultratech builds upon Microtech’s flagship design, introducing mechanical and functional improvements such as Dual-Fuel Drive Train™ and Crud Kutter™. The blade is made of Böhler M390MK steel, features an S/E Drop Point profile, a flat grind, and a Cerakote Sand Trooper finish, creating a combination designed for effective cutting, stable blade control, and high durability. The handle is made of 6061-T6 aluminum with the same finish, a titanium clip with a ceramic ball, a Thumb Slide, a Slide Lock, and a glass breaker highlight the technical and collectible nature of this variant.

Böhler M390MK – Microtech’s powder steel for modern OTF

Böhler M390MK is a high-performance powder steel developed for Microtech in collaboration with Böhler, designed with a focus on wear and corrosion resistance as well as long-lasting sharpness. In the Ultratech Gen IV model, this material performs well when cutting tape, film, cardboard, cord, straps, and plastics, where stable edge performance and predictable blade guidance are essential. The Cerakote Sand Trooper finish gives the blade the distinctive look of the Signature version while creating a technical, functional coating.

S/E Drop Point and flat grind – a versatile geometry for everyday work

The S/E Drop Point profile combines a strong tip with a functional edge line, making it well-suited for tasks requiring control, precise scoring, and effective cutting. The flat grind facilitates smooth blade glide through material, maintaining an optimal balance between cutting efficiency and durability. Full-tang grooves on both sides of the blade reinforce the model’s technical aesthetic and underscore its affiliation with the Ultratech line, which has long been one of the most recognizable benchmarks among OTF automatic knives.

Dual-Fuel Drive Train™ and Crud Kutter™ – Gen IV Mechanics

The Ultratech Gen IV utilizes the D/A OTF system, which allows the blade to be extended and retracted using the same Thumb Slide. The Dual-Fuel Drive Train™ solution improves the mechanism’s smoothness and reduces the force required to activate the knife, while maintaining fast, decisive blade action. The Crud Kutter™ system features angled cuts beneath the slide, limiting the accumulation of debris that could interfere with the mechanism’s operation. As a result, the fourth generation of Ultratech retains the practical nature of an EDC tool but offers a more refined user experience than previous versions.

Cerakote Sand Trooper and Titanium Clip – Signature Series in Action

The handle, made of 6061-T6 aluminum, is precision-machined to maintain the slim profile and reliable ergonomics typical of the Ultratech. The Cerakote Sand Trooper finish gives the knife a distinctive, collectible character, combining a light aesthetic with a technical surface pattern. Jimping on the spine and underside improves grip control, while the two-position titanium clip with a ceramic ball makes it easy to slide the knife into a pocket and reduces friction against the fabric. The handle is finished with a steel glass breaker, which expands the knife’s functionality in emergency situations.

Frequently Asked Questions

How to care for and sharpen the Böhler M390MK steel in the Ultratech Gen IV model?

Böhler M390MK steel should be cleaned and dried after use, especially after contact with moisture, sweat, or debris from cut materials. A diamond sharpener or a high-quality ceramic system works best for sharpening, as powder steel with high wear resistance requires an effective abrasive and a stable angle.

How does the D/A OTF mechanism work in the Ultratech Gen IV?

The D/A OTF mechanism allows the blade to be extended and retracted by moving the same Thumb Slide. The blade moves forward and backward along the handle axis, so the knife can be operated with one hand without the need for a traditional side-fold mechanism.

What is the Dual-Fuel Drive Train™?

Dual-Fuel Drive Train™ is the Gen IV drive system responsible for smoother blade extension and retraction. This solution reduces the force required to activate the slide, while maintaining the fast and decisive operation of the OTF mechanism.

What is the Crud Kutter™ for?

Crud Kutter™ is a series of angled cuts beneath the opening slider that helps reduce the buildup of debris that could interfere with the mechanism’s operation. It’s a practical solution for users who carry a knife every day.

What makes the Cerakote Sand Trooper variant stand out?

The Cerakote Sand Trooper variant belongs to the Signature Series and stands out with its consistent finish on the blade and handle. The light-colored coating gives the knife a collector’s appeal while maintaining the Ultratech’s technical, functional style.

Does the Microtech Ultratech Gen IV have a glass breaker?

Yes, the handle features a steel glass breaker. This is a structural element of the knife that expands its functionality in emergency situations, but it is not listed as a separate accessory in the technical specifications.
