Microtech LUDT Gen III S/E Tan Aluminum, Black M390MK Automatic Knife by Tony Marfione (1135-1TA)

The Microtech LUDT Gen III 1135-1TA is a spring-assisted folding knife featuring a Drop Point blade made of Böhler M390MK steel and a sandblasted 6061-T6 aluminum handle. The black blade, 3M non-slip inserts, and compact design create a practical version of one of Microtech’s most recognizable series.

The blade opens automatically with the push of a button, and its smooth operation is supported by a system of 24 silicon carbide ball bearings. The design is complemented by a black-finished titanium backspacer and a carry clip on the right side, with the tip pointing upward.

Böhler M390MK – steel developed for Microtech

The blade is made of Böhler M390MK steel, a special grade of M390 developed for Microtech in collaboration with Böhler. The material is distinguished by its high resistance to corrosion and abrasion, as well as its excellent edge retention, which well suits the requirements of an automatic folder intended for regular use.

Drop Point, flat grind, and black finish

The Drop Point profile provides a functional tip and a versatile cutting edge. The flat grind facilitates smooth gliding of the blade through material, while the black finish gives the knife a more subdued and technical look.

Sand-finish 6061-T6 aluminum and automatic mechanism

The handle is made of 6061-T6 aluminum in a sand color and features black, non-slip 3M inserts. A black-finished titanium backspacer completes the rear of the construction and blends seamlessly with the blade.

The blade opens automatically with the push of a button. The blade runs on 24 silicon carbide ball bearings, which ensure smooth and consistent movement of the mechanism. The clip is positioned on the right side in a tip-up configuration.

Technical Data

Frequently Asked Questions

How do I care for Böhler M390MK steel?

After use, it’s a good idea to clean the blade and dry it thoroughly. M390MK is highly corrosion-resistant, but periodically applying a thin layer of a suitable protective agent helps keep the surface in good condition.

At what angle should you sharpen the Microtech LUDT Gen III?

A good starting point is about 15–20° per side, preferably while maintaining the factory edge geometry. For the M390MK, it’s best to use high-performance abrasives suitable for steel with high wear resistance.

How does the LUDT Gen III automatic mechanism work?

Pressing the button releases the mechanism and causes the blade to open automatically. After use, the blade is folded manually by overcoming the spring tension.

How do you clean an aluminum handle with 3M inserts?

It’s best to clean the handle with a soft brush or a slightly damp cloth. Pay special attention to the edges of the inserts, where small particles of dirt can accumulate.

How to maintain ball bearings?

The area around the blade should be periodically cleaned of dust and fine debris. After cleaning, you can apply a small amount of a lubricant designed for knife mechanisms, taking care to avoid over-lubrication.
