- The Satre S600 Black is an exquisitely designed neck knife made from the excellent Bohler S600 steel. Responsible for the design is Daniele Dal Canto, one of the main instructors in F.I.S.S.S. (Italian Federation of Sports and Experimental Survival).

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.

S600 - a type of steel you don't often come across! High-speed cutting steel with high molybdenum, tungsten content and good quality, providing excellent hardness properties, achieving results and strength. The presence of cobalt causes small, unusual effects that increase in severity when they occur. S600 is hardened and cryogenically treated to achieve a hardness of 64 HRC. This gives a large capacity that is clearly visible. Produced in the Böhler-Uddeholm air steelworks.
Blade - sharp and solid Drop Point type, 5 mm thick, with a cutting edge ensuring extreme cutting performance. The Plain smooth blade is made with a flat grind (Flat Grind). Made of molybdenum high-speed steel Böhler S600 with 4.5% chromium content, which makes it a steel subject to oxidation. For this reason, Extrema Ratio has chosen a new blade coating - EXP DARK, which immortalizes the name of S600 steel, its unique hardness of 64 HRC and information about Cryogenic cryogenic treatment - features that emphasize the uniqueness of this alloy.
Handle - ergonomic, made of Austrian stainless steel Böhler-Uddeholm's S600. The contoured shape of the handle prevents accidental injury during use. Enlarged lanyard hole for pulling a lanyard or cord.
