529,27 €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 Arbiter S/E Black G10, Stonewashed F/S by Adam Marfione (104-12) – a large fixed-blade knife with a Bowie blade
Microtech Arbiter S/E Black G10, Stonewashed F/S by Adam Marfione (104-12) is a full-size fixed-blade knife designed as a robust tool for demanding outdoor, tactical, and utility tasks. The model features a robust construction, a long S/E (Single Edge) blade with a Clip Point / Bowie profile, and a handle made of durable G10 composite. The blade is made of Böhler M390 steel, features a flat grind, and a Stonewashed finish, creating a combination focused on high durability, effective cutting, and stable blade control. The partially serrated lower edge and serrated upper section enhance functionality when working with ropes, straps, and fibrous materials. The Kydex sheath with carbon fiber laminate and M.O.L.L.E. mounting facilitate safe carrying of the knife on your gear.
Böhler M390 – Microtech powder steel for large fixed-blade knives
Böhler M390MK is a high-performance powder steel developed for Microtech in collaboration with Böhler, designed with an emphasis on wear resistance, corrosion resistance, and long-lasting sharpness. In the Arbiter model, this material performs well when working with straps, ropes, tapes, cardboard, plastics, and technical materials, where edge stability and resistance to heavy use are essential. The Stonewashed finish gives the blade a matte, technical look and helps mask minor marks that occur during regular use.
S/E blade, Clip Point / Bowie profile and flat grind – power, reach, and cutting control
S/E (Single Edge) blade with a Clip Point / Bowie profile combines a long blade line with a distinctly pointed tip, which facilitates precision work, scoring, and penetration of the material. The flat grind supports effective guidance of the wide blade through the material being cut, maintaining a good balance between cutting efficiency and structural strength. A distinctive sharpened section on the spine enhances tip performance, while serrations partially located on the lower and upper edges improve effectiveness with fibrous materials, ropes, and straps.
Black G10 and full tang – a handle for heavy-duty use
The handle, made of G10, is shaped for a stable grip on a large fixed-blade knife. Contoured finger grooves help control the tool during heavy-duty cutting, while jimping on the handle and the blade spine enhance handling confidence. The full-tang construction ensures high rigidity, and the Microtech screw-mounted scales emphasize the model’s utilitarian character. The protruding tang section can serve as an emergency glass breaker, and the lanyard hole allows for the use of a safety or decorative lanyard.
Kydex / Carbon Fiber Laminate and M.O.L.L.E. – safe carrying of a large knife
The sheath, made of Kydex / Carbon Fiber Laminate, is designed to securely hold a large knife in various positions. The rigid construction protects the blade, reduces the risk of accidental deployment, and facilitates quick access to the tool. The M.O.L.L.E. attachment system allows the sheath to be clipped to a belt, vest, backpack, or other gear, in both vertical and horizontal configurations. This solution fits well with the Arbiter’s character as a large field and tactical knife.

Frequently Asked Questions
How do I care for and sharpen the Böhler M390 steel in the Arbiter model?
Böhler M390 steel should be cleaned and dried after use, especially after contact with moisture, sweat, or debris from cut materials. For smooth sections, a diamond sharpener or a high-quality ceramic system works best, while serrations require appropriate ceramic rods or serration tools.
What makes the S/E Clip Point Bowie blade stand out?
The blade S/E (Single Edge) with a Clip Point / Bowie profile combines a long cutting edge, a strong tip, and a distinctive spine line. This geometry works well for precision work, cutting technical materials, and tasks requiring a long blade reach.
How is the serration arranged in this variant?
The F/S (Full Serreted) variant features partial serrations on the lower edge and partial serrations on the upper section of the blade. This design enhances performance when working with ropes, straps, tapes, and fibrous materials.
What is the Kydex / Carbon Fiber Laminate sheath used for?
The Kydex / Carbon Fiber Laminate sheath securely holds the knife and protects the blade during transport. The M.O.L.L.E. attachment allows you to carry the knife on a belt, backpack, or gear in either a vertical or horizontal configuration.
Does the Microtech Arbiter have a feature that can function as a glass breaker?
Yes, the protruding section of the tang can serve as an emergency glass breaker. This is part of the knife’s design, not a separate accessory. There is also a hole in the same area for a safety or decorative lanyard.
