Microtech Ultratech Gen IV T/E Topographic Black / Orange Camo – OTF Tanto M390MK Automatic Knife by Tony Marfione

The Microtech Ultratech Gen IV T/E Topographic Black / Orange Camo Aluminum OTF folding knife, Topographic Black / Orange Camo M390MK by Tony Marfione (11234-1TPBKORCS) is an OTF automatic knife featuring a Tanto blade, a 6061-T6 aluminum frame, and a striking black-and-orange topographic pattern. This model is part of the Signature Series and utilizes Böhler M390MK steel and a Double Action OTF mechanism.

The T/E profile features a distinctly defined front section, a strong tip, and a smooth Plain Edge. The thumb slide automatically extends and retracts the blade, while the titanium clip with a ceramic ball can be mounted on the right or left side of the handle in a tip-down position.

Böhler M390MK – Durable Steel for a Folding Knife

The blade is made of Böhler M390MK stainless steel, manufactured to Microtech’s specifications. The material offers high corrosion resistance, good edge stability, and properties suited to the precision design of an OTF automatic knife.

Tanto, Plain Edge, and Topographic Cerakote

The Tanto profile features a strong tip and a distinct transition between the main and front sections of the edge. The Flat grind supports effective cutting, while the smooth Plain Edge facilitates controlled blade guidance. The blade and handle are coated with a black-and-orange Cerakote finish featuring a topographic pattern.

Gen IV mechanics and aluminum housing

The Dual-Fuel Drive Train™ system is responsible for automatically extending and retracting the blade. The Crud Kutter™ system helps remove fine debris from the mechanism, and the milled 6061-T6 aluminum housing ensures rigidity while maintaining a manageable weight.

Technical Data

Frequently Asked Questions

How do I care for Böhler M390MK steel?

The blade should be cleaned and dried after use, especially after contact with moisture, salt, or food substances. For long-term storage, you can apply a thin layer of a knife preservative.

How do you sharpen a Tanto blade?

The main and front sections of the edge should be sharpened separately, maintaining a distinct transition between them. Rounding the corner during sharpening would alter the characteristic geometry of the Tanto profile.

How do you operate the Double Action OTF mechanism?

Pushing the slide forward extends the blade, while pulling it back retracts the blade into the handle. Each movement should be performed firmly all the way to the end of the slide, without stopping the slide in an intermediate position.

Does the Crud Kutter™ eliminate the need to clean the knife?

No. The system helps minimize the impact of fine debris on the mechanism, but the knife still requires regular cleaning. Pay special attention to the blade opening, the guide rails, and the area around the slide.

How do I adjust the reversible clip?

The titanium clip can be mounted on the right or left side of the handle in the tip-down position. A ceramic ball reduces resistance when sliding the knife into a pocket and minimizes contact between the clip and the fabric.
