340,94 €This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
Microtech MSI S/E Natural Clear Frag Aluminium, Black M390MK by Anthony Marfione (210-1FRNC) – EDC folding knife with Frag Aluminium handle and Ram-Lok lock
The Microtech MSI S/E Natural Clear Frag Aluminium, Black M390MK by Anthony Marfione (210-1FRNC) is a folding EDC knife with a robust, technical design, engineered for users who demand durability, ambidextrous operation, and a secure grip for demanding tasks. The Böhler M390MK steel blade, sheepfoot profile, flat grind, and black coating create a system focused on durability, controlled blade guidance, and effective cutting of everyday materials. The handle, made of 6061-T6 aluminum in the Natural Clear Frag finish, combines high rigidity, a distinctive texture, and a stable grip. The Ram-Lok lock, manual opening via the thumb hole, ball bearings, and right/left clip, along with the tip-up feature, reinforce the practical nature of the MSI model.
Böhler M390MK – Microtech powder steel for demanding EDC
Böhler M390MK is a high-performance powder steel developed in collaboration between Microtech and Böhler, designed for high resistance to wear, corrosion, and long-lasting sharpness. In the MSI model, it performs well when cutting cardboard, plastics, tape, cord, packaging, and utility materials, where edge durability and predictable blade performance are essential. The black protective coating gives the blade a technical look, reduces glare, and helps protect the surface during regular use.
Sheepfoot and flat grind – cutting control and robust working geometry
The sheepfoot profile provides good control over the cutting line and reduces the aggressiveness of the tip, which is useful for technical work, opening packages, and cutting flat materials. The flat grind facilitates smooth blade guidance through cardboard, tape, plastics, and other EDC materials, ensuring optimal working geometry. The serrated thumb rest on the blade spine improves pressure control and allows for more stable edge guidance during heavier cutting.
Natural Clear Frag Aluminum and Ram-Lok – grip, rigidity, and ambidextrous operation
The handle, made of 6061-T6 aluminum, features a Frag texture that improves grip and gives the knife a distinctive, technical look. The aluminum grips create a rigid construction resistant to daily wear and tear, while the Titanium backspacer reinforces the entire assembly and increases the Handle’s durability. Ram-Lok functions as a crossbar lock, accessible from both sides of the Handle, making it easy to use for both right- and left-handed users.
Why choose the Microtech MSI S/E Natural Clear Frag Aluminum for your gear?

Frequently Asked Questions
How do I care for and sharpen the Böhler M390MK steel in the Microtech MSI model?
Böhler M390MK steel should be cleaned and dried after use, especially after contact with moisture, sweat, or debris from cut materials. For sharpening, a diamond sharpener or a high-quality ceramic system works best, as powder steel with high wear resistance requires an effective abrasive and a stable angle guide.
How does the Ram-Lok lock work?
Ram-Lok uses a crossbar that moves within the Handle guides. When opened, the bar locks the rear part of the blade, preventing it from folding. To unlock the knife, pull the bar backward; it is accessible from both sides of the Handle, making it easy to operate with either the right or left hand.
What makes the Frag Aluminum handle stand out?
Frag refers to an aluminum handle with a texture inspired by the fragmentation pattern of hand grenades, which improves grip stability and gives the knife a technical character. 6061-T6 aluminum ensures rigidity, mechanical resistance, and good durability for everyday carry.
What tasks is the sheepfoot profile best suited for?
The sheepfoot profile works well for tasks requiring edge control, such as cutting cardboard, tape, plastic wrap, packaging, and technical materials. The tip’s limited aggressiveness helps guide the blade without an excessive risk of accidentally piercing the material.
Is the Microtech MSI Natural Clear Frag suitable for left-handed users?
Yes, the MSI design is optimized for two-handed use. Ram-Lok is accessible from both sides of the Handle, the blade hole facilitates manual opening with the right or left hand, and the right/left tip-up clip allows you to adjust the carrying style to your preference.
