Microtech MSI – Claw Burst Camo folding knife with full serration

Microtech MSI S/E Claw Burst Camo Tri-Grip Polymer, Black M390MK F/S by Tony Marfione (210T-3PMCWC-Z4) is a manual folding knife from the Microtech Standard Issue line, designed for users seeking a sturdy folder with ambidextrous operation, a Ram-Lok lock, and an aggressive, serrated edge. The F/S / Full Serrated variant is designed for quickly cutting fibrous materials, ropes, straps, and plastics, where the serrated edge provides a distinct performance advantage.

The blade, made of Böhler M390MK steel, features a Sheepfoot profile, a flat grind, and a black protective coating, creating a configuration with a technical, tactical character. The handle, made of polymer with a Claw Burst Camo finish, features a Tri-Grip texture that improves grip stability. Thumb-hole opening, a left/right-hand clip, tip-up mechanism, and an aluminum backspacer enhance the practicality of this full-size MSI.

Böhler M390MK – Powder Steel for Heavy-Duty Use

Böhler M390MK is a powder steel developed for Microtech in collaboration with Böhler, designed for high wear resistance, corrosion resistance, and long-lasting sharpness. In the fully serrated version, the steel performs well in applications where the blade cuts through hard, slippery, or fibrous materials.

The black protective coating gives the blade a tactical look and enhances its color coordination with the Claw Burst Camo. Combined with the F/S serrated edge, this model becomes more specialized than the smooth-edge versions, while retaining the versatile MSI mechanics and the convenience of everyday carry.

Sheepfoot F/S and flat grind – serrated cutting efficiency

The Sheepfoot profile provides good control over the cutting line and reduces the aggressiveness of the tip, which increases predictability during use. The F/S / Full Serrated version features a fully serrated edge, allowing it to handle ropes, straps, tapes, technical textiles, and fibrous materials more effectively.

The flat grind helps guide the blade through the material, and the thumb hole allows you to comfortably open the knife with either your right or left hand. The serrated thumb rest on the blade spine improves pressure control, especially when the serrated edge is under heavy load.

Claw Burst Camo Tri-Grip Polymer and Ram-Lok

The handle, made of polymer, features a Tri-Grip texture that increases grip and helps maintain a secure hold when working with gloves or in more challenging conditions. The Claw Burst Camo graphic finish gives the knife a distinctive look and combines functional design with Microtech’s bold styling.

The Ram-Lok lock acts as a crossbar accessible from both sides of the Handle. This design makes the knife easy to use for both right- and left-handed users, while ensuring the blade remains securely locked in the open position. The right/left tip-up clip allows you to customize how you carry the knife, and the aluminum backspacer reinforces the Handle’s construction.
