797,73 €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.
Estrema Black G10, Dark Stone is the result of the engineering precision of the Extrema Ratio brand , designed for the G.O.I. (Navy Raiders Operational Group), responding to the needs of professionals working in the field - operators, soldiers, rescuers and survival enthusiasts. It was created as a multi-purpose tool for use in extreme conditions, where uncompromising durability and maximum functionality count . Blade made of hardened N690 steel (54 HRC) offers excellent wear resistance and the ability to be sharpened quickly in the field. The Dark Stone finish used reduces susceptibility to corrosion and eliminates light reflections to maintain a low optical profile in operational conditions. Handle made of G10 allows for two types of gripping - for hard knocks or precision manipulation. The mounting system for the optional hammer (carbon steel) increases the versatility of the design. The whole is placed in a technical kit with a Kydex sheath, clip and safety cable, which makes the Estrema a tool prepared for any challenge.
N690 - corrosion-resistant, high-carbon 1.07% (C), martensitic chromium steel 17.30% (Cr) with molybdenum 1.10% (Mo), vanadium 0.10% (V) and cobalt 1.50% (Co) for structural uniformity. It features exceptionally high corrosion resistance and long edge retention. One of the best tool steels in the world today. Achieves a hardness of 57-60 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - massive, the shape and balance of which enable effective performance of a variety of tasks - from classic chopping and chiseling to technical operations in difficult terrain. The profile of the blade provides impact force and the right geometry for forcing through obstacles or undermining structural elements. Böhler N690, a steel with excellent corrosion resistance, has been hardened to a hardness of 54 HRC, providing a balance between durability and field sharpening practicality. The matte Dark Stone coating improves resistance to the elements and reduces reflections - crucial in tactical operations. The Blade 's tip is equipped with a functional extension for balancing or splitting, which significantly expands the tool's range of applications. This is a versatile tactical component, which combines the function of a hatchet, chisel and crowbar in one compact form.
Handle - grips are made of G10 - a composite material that provides excellent mechanical strength and resistance to extreme temperatures, moisture and chemicals. This material guarantees reliability both in dry sand and in heavy rain or snow. Thanks to the two-position geometry of the handle, the user can operate the tool both forcibly and precisely. The traditional grip allows for strong strokes, while the front grip provides greater control in tight spaces. The textured surface improves grip, and the refined shapes reduce hand fatigue during long work. In addition, the tapered end of the Handle can be used as a tool for undermining, cutting sheet metal or forcing entrances, increasing the hatchet's functionality. Estrema can be retrofitted with a modular carbon steel hammer (not included in the basic kit), mounted through a spring-loaded system with a safety catch.
Sheath - made of Kydex with a retention system and belt clip, as well as a safety cable. This solution is designed for users who need a tool that exceeds the capabilities of classic hatchets.
