- Muela 85-161.D a full-sized fixed-blade knife with a Bowie profile. Crafted from Nitro‑42 stainless steel, coated with a protective black finish, it features a durable handle made of rubber and zamak. Engineered for extreme field and tactical applications

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.

Nitro-42 - modified 420 steel with higher carbon content doped with nitrogen, which allows for higher hardness up to 62 HRC and higher corrosion resistance.
Blade - bowie profile. The rounded back with a pronounced downswing leads to a thin tip, allowing precise punctures and angled cuts. The blade is made of Nitro-42 steel, enriched with nitrogen, which provides increased corrosion resistance, hardness and stability of the cutting edge in field conditions. The black coating masks light reflections while protecting against micro-damage. The back features a functional saw, allowing cutting through rope, plastic or wood. Blade offers a natural balance between length, thickness and profile, which translates into efficiency in both power and precision work.
Handle - is based on a design where Guard and Pommel made of zamak in combination with molded textured rubber grips , provide durability, stiffness and resistance to mechanical damage. The grip surface is designed for confident handling in wet or harsh conditions - a non-slip texture and pronounced finger indentations increase control, while the extension of the buttstock prevents the hand from slipping on the blade. Guard and head are made of blackened zamak, which not only improves safety, but also stiffens the overall design. The ergonomics of the grip has been optimized for long-term work - regardless of the position, the user gains stability and comfort.
