£100.03This 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.

Blade - extremely sharp with a Drop Point profile, 2.5 mm thickness with a clearly defined belly of the blade. Made of good sharpness, durable high-grade N690 high-grade stainless steel with a hardness of 58 HRC, manufactured at the Austrian Böhler-Uddeholm steel mill. The blade is finished with a masking small scratches, a non-reflective Stone Washed coating. Smooth blade (Plain type) was made with full flat cut (Full Flat Grind) which ensures strength, excellent cutting edge geometry and extreme cutting performance. Robust blade blockade: Liner-Lock type.
Handle - in HCS (Hybrid Coyote Sage) color. Liners made of stainless steel and technopolymer (reinforced nylon) ensure lightness and structural strength. The open construction, called „open-backed” simplifies cleaning and maintenance. A solid metal left / right side clip (deep-pocket metal clip) allows you to carry the knife deep in the pocket (discreetly) in the tip-up position. In the back of the cladding was placed oval gap (lanyard hole) for the cord.
Technopolymer - also known as the successor to metal. Modern material with a high percentage of glass fibers associated with the polymer base and the presence (or not) of aramid (synthetic fibers, including Kevlar). It is characterized by unusual mechanical and thermal parameters. Advantages: corrosion resistant, low weight, no maintenance (low friction coefficient), electrical insulation (prevents electric conduction), no reaction to magnetic field, any colors.
