Microtech MSI Ram-Lok S/E Black Tri-Grip Polymer, Stonewashed F/S M390MK by Tony Marfione – a folding knife with a fully serrated blade

The Microtech MSI Ram-Lok S/E Black Tri-Grip Polymer folding knife, Stonewashed F/S M390MK by Tony Marfione (210T-12PMBK) is a full-size folding knife featuring a fully serrated Modified Sheepsfoot blade made of Böhler M390MK steel, a RAM-LOK® lock, and a black injection-molded polymer handle. The Tri-Grip texture provides a secure grip, while the Stonewashed finish gives the blade a rugged, utilitarian look.

The blade is opened manually using a large opening accessible from both sides. Ball bearings ensure smooth operation of the mechanism, and the repositionable deep-carry clip allows for tip-up carry on either the right or left side of the handle.

Böhler M390MK and a flat grind

The blade is made of Böhler M390MK stainless steel, which provides high corrosion resistance and good edge retention. The Flat grind supports effective cutting and the stable geometry of the wide blade.

Modified Sheepsfoot and Full Serrated

The Modified Sheepsfoot profile features a lowered tip and a long cutting edge. The Full Serrated edge excels at cutting fibrous materials, ropes, straps, and belts. The Stonewashed finish helps minimize the appearance of minor signs of everyday use.

Black Tri-Grip Polymer and RAM-LOK®

The black handle is made of injection-molded polymer and reinforced with steel liners. The Tri-Grip texture improves grip, control, and ergonomic comfort. The RAM-LOK® lock secures the blade when open and allows for comfortable operation from both sides of the handle.

Technical Data

Frequently Asked Questions

How do I care for Böhler M390MK steel?

After use, clean the blade and dry it thoroughly. Before long-term storage, apply a thin layer of preservative, especially after contact with moisture, salt, or organic substances.

How do I sharpen the Full Serrated edge?

Sharpen the serrations one at a time using a ceramic rod or a file with a diameter matching their profile. Maintain the factory angle and avoid removing too much material, which could flatten or widen the serrations.

How does the RAM-LOK® lock work?

RAM-LOK® uses a crosswise-sliding component that locks the blade when it is fully extended. The mechanism can be conveniently operated with either the right or left hand.

How do I clean the black Tri-Grip handle?

The handle can be cleaned with a soft brush and mild detergent. The grooves in the Tri-Grip texture should be thoroughly rinsed, and then the surface, steel liners, and the area around the lock should be dried.

How do you maintain the pivot pin?

The area around the pivot pin should be regularly cleaned of dust and small debris. After cleaning, you can apply a small amount of a light lubricant designed for knife mechanisms.
