Microtech UTX-85 Gen IV – a compact OTF automatic knife in the Jedi Master variant

Microtech UTX-85 Gen IV D/E Jedi Master Aluminum, Green M390MK by Tony Marfione (12324-1JM) is a compact OTF automatic knife that retains the functionality of the larger Ultratech but offers a more manageable size for everyday carry. The UTX-85 is approximately eighty-five percent the size of Microtech’s flagship model, making it fit well in the hand and remain comfortable for one-handed use. The fourth generation improves ergonomics, mechanism smoothness, and ease of maintenance, while retaining Microtech’s signature speed and precision.

The Jedi Master variant stands out with its distinctive styling, featuring a green blade and a matching handle finish. The D/E / Double Edge blade is made of Böhler M390MK steel, and the flat grind ensures effective blade glide through the material. The Dual-Fuel Drive Train™ mechanism, the Crud Kutter™ feature, the Thumb Slide, a titanium clip, and a glass breaker combine to create a compact OTF automatic knife suitable for both practical use and collecting.

Böhler M390MK – Microtech steel in a compact OTF

Böhler M390MK is a special grade of M390 steel developed for Microtech in collaboration with Böhler. The material was designed with an emphasis on high wear resistance, corrosion resistance, and long-lasting sharpness. In the UTX-85 Gen IV model, the steel performs well for EDC tasks such as cutting tape, cardboard, plastic wrap, cord, straps, and plastics, where edge stability and consistent blade performance are important.

The green blade finish emphasizes the character of the Jedi Master variant and distinguishes it from standard utility versions. Combined with the aluminum body, it creates a distinctive, collectible aesthetic that still draws on Microtech’s signature technical design. This variant is for those who expect an OTF automatic knife with compact dimensions, a robust character, and premium-grade materials.

D/E Double Edge and flat grind – symmetry and precise control

The D/E / Double Edge profile utilizes a symmetrical blade geometry with a centrally aligned tip. This design improves precision during pinpoint operations and gives the knife a distinctly technical character. The double-sided blade geometry is well-suited to the OTF design, where the speed of blade deployment is combined with simple, axial blade guidance from the handle.

The flat grind facilitates smooth cutting through material while maintaining a good balance between cutting performance and structural strength. The fuller grooves on both sides of the blade reinforce Microtech’s signature look, and the UTX-85’s compact format maintains high functionality while being smaller than the full-size Ultratech.

Dual-Fuel Drive Train™, Crud Kutter™, and Slide Lock

The Dual-Fuel Drive Train™ mechanism ensures smoother blade deployment and retraction and reduces the force required to activate the slide. In practice, the user gets a fast, decisive OTF mechanism that can be operated with a single thumb motion. The Thumb Slide allows you to both extend and retract the blade without changing your grip, which is one of the key advantages of the out-the-front design.

The Crud Kutter™ solution uses angled slits beneath the slide to help reduce the buildup of debris that could interfere with the mechanism’s operation. The Slide Lock stabilizes the blade in the open position, and the automatic push/pull system allows you to maintain full control over opening and closing the knife.

Jedi Master Aluminum, titanium clip, and glass breaker

The handle is made of 6061-T6 aluminum, a lightweight and durable alloy used in structures requiring a good weight-to-stiffness ratio. The Jedi Master finish gives the knife a distinctive, collectible character, while the milled grooves and jimping enhance grip control when operating the slide and working with the blade.

The right/left-hand tip-down clip allows the knife to be carried on either side, and the clip’s titanium construction underscores the premium nature of this model. The handle features a glass breaker, which expands the knife’s functionality in emergency situations. The UTX-85’s slim profile makes it easy to carry daily, and its compact size ensures it remains comfortable even for users who prefer smaller OTF automatic knives.
