Microtech MSI – full-size folding knife with a Tri-Grip handle and red backspacer

Microtech MSI S/E Black Tri-Grip Polymer, Red Back Strap, Stonewashed M390MK by Tony Marfione (210T-10PMBK-A5) is a manual folding knife from the Microtech Standard Issue line, designed as a durable EDC folder offering high functionality and comfortable two-handed operation. The model features a Ram-Lok lock, a contoured polymer handle, and thumb hole opening, making it suitable for both everyday tasks and more technical applications.

The Böhler M390MK blade, Sheepfoot profile, flat grind, and Stonewashed finish create a practical configuration for cutting cardboard, tape, cord, plastics, and utility materials. The black Tri-Grip Polymer handle with a red backspacer gives the knife a distinctive look, and the right/left tip-up clip allows you to customize how you carry it to suit your preferences.

Böhler M390MK – Microtech’s powder steel for everyday use

Böhler M390MK is a special grade of M390 steel developed for Microtech in collaboration with Böhler. The material offers high wear resistance, good corrosion resistance, and long-lasting sharpness. In the MSI model, it performs well when working with materials typical for EDC: packaging, cardboard, plastics, tapes, cords, and technical fabrics.

The Stonewashed finish gives the blade a slightly matte, workhorse look and helps mask minor signs of regular use. Combined with the black handle and red back strap, it creates a variant with a technical yet more dynamic style than the standard single-color versions.

Sheepfoot and flat grind – cutting control in an EDC folder

The Sheepfoot profile allows for precise guidance of the cutting edge and reduces the aggressiveness of the tip, which is useful for opening packages, cutting cardboard, and working with flat materials. This geometry increases control over the blade and is well-suited for a utility folder designed to be reliable in everyday use.

The flat grind ensures smooth glide of the blade through the material and good working geometry. The thumb hole makes it easy to open the knife manually with either the right or left hand, and the serrated thumb rest on the blade spine improves pressure control during heavier cutting.

Tri-Grip Polymer, Red Back Strap, and Ram-Lok lock

The handle, made of polymer, features a Tri-Grip texture that improves grip stability and enhances control of the knife when working in wet conditions, while wearing gloves, or during dynamic hand positioning. The red back strap provides a distinctive visual accent while also serving as a structural element of the Handle.

The Ram-Lok lock features a crossbar accessible from both sides, making the knife comfortable for both right- and left-handed users. The right/left tip-up clip enhances the practicality of everyday carry, and the handle design allows for secure blade control during tasks requiring greater precision.

Technical Data

Frequently Asked Questions

How do I care for and sharpen the Böhler M390MK steel in the MSI model?

Böhler M390MK steel should be cleaned and dried after use, especially after contact with moisture, sweat, or dirt. A diamond sharpener or CBN system works best for sharpening, as powder steel requires an effective abrasive.

How does the Ram-Lok lock work?

Ram-Lok uses a crossbar that moves within the handle’s guides. When opened, the crossbar locks the rear of the blade, and access from both sides facilitates use with either the right or left hand.

What makes the Sheepfoot profile stand out?

Sheepfoot provides good control over the cutting line and reduces the aggressiveness of the tip. This geometry works well for opening packages, cutting cardboard, and working with flat materials.

What is Tri-Grip Polymer?

Tri-Grip Polymer is a polymer handle with a textured surface that improves grip. This design enhances grip stability and makes it easier to guide the knife during everyday and technical tasks.

Is the Microtech MSI suitable for left-handed users?

Yes, the MSI’s design supports ambidextrous use. The Ram-Lok is accessible from both sides of the Handle, the thumb hole makes it easy to open with either hand, and the clip can be repositioned.
