Microtech Nemesis IV D/E Marfione Select OTF Knife Black Aluminum, Black DLC F/S M390MK by Tony Marfione (1152-3DLCTMS1)

Microtech Nemesis IV D/E Marfione Select Black Aluminum, Black DLC F/S M390MK OTF Knife by Tony Marfione (1152-3DLCTMS1)

The Microtech Nemesis IV 1152-3DLCTMS1 is a full-size OTF knife from the Marfione Select series, featuring a symmetrical Double Edge blade made of Böhler M390MK steel. The black aluminum handle and Black DLC coating create a cohesive, technical aesthetic, and one edge of the blade is fully serrated.

The Nemesis IV has an overall length of 259.0 mm, a blade length of 112.0 mm, and a weight of 119.0 g. The design utilizes a Single Action OTF mechanism—the button automatically extends the blade, but the mechanism requires manual cocking before the next cycle. This feature distinguishes the Nemesis IV from typical Double Action OTF knives.

Böhler M390MK – high wear resistance

The blade is made of Böhler M390MK steel, which provides high abrasion resistance and very good corrosion resistance. In the case of a long Double Edge blade, this ensures good durability of both the smooth and serrated edges. This steel performs well in applications requiring high surface hardness and long-lasting sharpness.

Double Edge, Flat, and Black DLC Full Serrated

The symmetrical Double Edge blade features a flat grind and a center-aligned tip. One edge is smooth, while the other is fully serrated, which increases cutting efficiency when handling fibrous materials. The black DLC coating gives the blade a uniform appearance, increases the surface’s wear resistance, and limits direct contact between the steel and the environment.

Black Aluminum and Single-Action Mechanism

The handle is made of black 6061-T6 aluminum. Its design also incorporates the rear section, which serves as a backspacer, eliminating the need for a separate component in that area. The Single Action mechanism works with a Button Lock, and the blade opens automatically with the push of a button. After the blade is extended, the mechanism must be manually re-tensioned.

Technical data

Frequently Asked Questions

What are the properties of Böhler M390MK?

M390MK is characterized by high abrasion resistance and very good corrosion resistance. Thanks to this, it maintains its sharpness well on both the smooth and serrated parts of the blade.

How do you sharpen a full-serrated edge?

It’s best to sharpen the serrated edge individually in each space between the serrations, using a narrow ceramic or diamond rod of the appropriate diameter. The smooth edge on the opposite side can be sharpened using standard sharpening stones or a sharpening guide system.

How does the Single Action OTF mechanism work?

Pressing the button automatically extends the blade, but the mechanism does not retract it automatically. After use, you must manually retract the blade and reset the mechanism before opening it again.

What are the benefits of the Black DLC coating?

DLC increases the surface’s resistance to wear and helps reduce the effects of moisture and minor wear and tear. At the same time, it gives the blade a uniform, black finish.

How does this version differ from the Stonewashed variant?

The construction, steel, and mechanism remain the same, but the 1152-3DLCTMS1 variant features a black DLC coating and a single Full Serrated edge. It is this blade configuration that is the main difference from the Stonewashed version.
