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.

N690Co - cobalt-rich 1.65% (Co) corrosion-resistant, high-carbon 1.07% (C) martensitic chromium steel 17.30% (Cr) with molybdenum 1.10% (Mo), vanadium 0.10% (V). Developed to provide better wear resistance compared to the original Böhler N690 steel, but with higher cobalt (Co) content in its composition. It features exceptionally high corrosion resistance and long edge retention. One of the best tool steels in the world today. Hardened in the range of 58-61 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Acid Stone Washed - Acid etching uses a chemical reaction between an acid etching solution and the blade steel. The blade was then given a Stone Washed finish to mask minor scratches.
Blade - wide, Tanto type finished with a scratch-masking Acid Stone Washed finish. A mixed grind was used in this case, in the back part it is a high, concave grind for cutting and precision work, the so-called Hollow Ground Primary Bevel. In the front part we have a high Flat Ground reinforcing tip grind. To improve piercing capabilities, an unsharpened false blade is brought out at the top. 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 - liners made of FRN (Fiberglass Reinforced Nylon), a lightweight material, insensitive to weather conditions, resistant to chemicals and mechanical damage. Chamfered edges of the covers eliminate sharp edges and surface texturing improves grip security. 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.
