The Microtech UTX-70 Gen IV D/E Black Aluminum, Stonewashed M390MK OTF automatic knife by Tony Marfione (11474-10) is a compact OTF Double Action automatic knife featuring a double-edged Dagger blade, a black 6061-T6 aluminum handle, and a next-generation mechanism.

The UTX-70 Gen IV has an overall length of 152.40 mm and weighs 39.69 g, making it compact enough for everyday carry. Sliding the slide automatically extends or retracts the blade, and the reversible clip allows for tip-down carry on either the right or left side of the handle.
Böhler M390MK and flat grind
The double-edged blade is made of Böhler M390MK stainless steel, developed specifically for Microtech knives. The material provides high corrosion resistance and good edge retention. The Flat grind promotes efficient cutting, while the symmetrical Dagger profile features two smooth Plain Edge cutting edges.
Dagger Double Edge and Stonewashed
The Dagger, Double Edge profile is characterized by a centrally located tip and two sharpened edges. The Stonewashed finish gives the blade a subdued, utilitarian look and helps minimize the visibility of minor scratches and scuffs that occur during use.
Dual-Fuel Drive Train™, Crud Kutter™, and 6061-T6 aluminum
The black handle is made of 6061-T6 aluminum. Side grooves enhance grip and control of the compact body. The Dual-Fuel Drive Train™ mechanism ensures smooth blade extension and retraction, while the Crud Kutter™ system helps direct debris away from key mechanical components. Standard Torx screws facilitate proper maintenance, and the integrated glass breaker expands the knife’s emergency functionality.

Frequently Asked Questions
How do I care for Böhler M390MK steel?
After use, clean the blade and dry it thoroughly. Despite its high corrosion resistance, do not allow moisture, salt, or corrosive substances to remain on it. Before long-term storage, you can apply a thin layer of preservative.
How to sharpen a double-edged Dagger blade?
Each edge should be sharpened separately, maintaining a consistent angle and symmetry on both sides of the blade. Near the centrally positioned tip, reduce the pressure to avoid altering its geometry or rounding off the tip.
How does the Double Action OTF mechanism work?
Pushing the slide forward automatically extends the blade, while pulling it back retracts the blade. The Dual-Fuel Drive Train™ mechanism ensures consistent operation in both directions.
How do you clean the Crud Kutter™ system?
Crud Kutter™ helps reduce debris buildup but does not replace regular maintenance. Protect the knife from sand, lint, and excess oil. Use only a small amount of a cleaner designed for OTF knives on the mechanism.
How to care for the Stonewashed finish on the blade?
It is best to clean the blade with a soft cloth and mild detergent. Do not use polishing compounds or abrasive materials, as they may alter the characteristic appearance of the Stonewashed surface.
