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.

Elmax - considered "the best all-around knife steel" a modern alloy steel with a high content of chromium 17.30% (Cr), carbon 1.70% (C), vanadium 3.00% (V), molybdenum 1.00% (Mo), silicon 0.80% (Si). Hardened in the range of 57-62 HRC. Produced by powder metallurgy, it is characterized by extreme edge holding, high wear and corrosion resistance, and dimensional stability. Manufactured at Böhler-Uddeholm steel mills in Austria.
PVD (Physical Vapor Deposition) - the resistance of the surface of the wedge and cutting edge is enhanced by a vacuum deposition method used to deposit thin films by condensing an evaporated form of the desired material onto the surface of the workpiece. The coating method involves a purely physical process such as high-temperature vacuum evaporation followed by condensation. The applied coating has a very high hardness which significantly increases the resistance of the blade to rust and abrasive wear.
Blade - wide, Drop Point type with black PVD coating. The generous belly extends the length of the cutting edge in relation to the length of the blade converging towards the needle-sharp tip of the knife. The thickness of the blade provides high strength while the high, flat grind gives excellent cutting edge geometry and extreme cutting performance. Ball bearings support the opening of the blade with a quick flipper (index-finger flipper) when opened acting as a stag. We can also open the knife using the oval opening in the blade (thumb hole). The whole thing is locked with a proven and popular liner lock.
Handle - facings made of Carbon Fiber, a lightweight, weatherproof, chemical-resistant material. Chamfered edges of the covers eliminate sharp edges and surface texturing improves grip confidence. The solid backspacer to which the facings are attached guarantees the rigidity and strength of the entire structure. A two-position (right/left) lightweight wire clip allows the knife to be carried in tip-up position, with the tip of the blade upward. Above the clip a hole for threading a safety or decorative cord.
