- Tuscan S600 Green G10, Exp Dark, a durable premium tactical knife designed for operational use in difficult terrain. S600 steel, a G10 handle and a sheath with a MOLLE system make it a reliable tool in all conditions.

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.
The Tuscan S600 Green G10, Exp Dark is designed for professionals and enthusiasts who need tools tailored to the realities of field work. Developed by Extrema Ratio, it is a continuation of the Tuscan line, complemented by an improved design and top-quality materials that increase the knife's durability and functionality. At the heart of the design is a blade made of high-quality Böhler S600 steel, cryogenically hardened to a hardness of 64 HRC and resistant to abrasion and extreme loads. The matte EXP DARK coating protects the steel from corrosion and eliminates light reflections, which is particularly important in tactical environments. The ergonomically designed green G10 handle guarantees a reliable grip, even in difficult weather conditions. The set includes a Cordura sheath, compatible with the MOLLE system and a thigh strap, allowing for complete freedom of configuration. This is a tool for those who are looking for a combination of functionality and extreme durability without compromise.
S600 - a type of steel you don't often see! High-speed steel with a high molybdenum and tungsten content and good vanadium content, ensuring excellent hardness, wear resistance and strength. The presence of cobalt promotes the formation of small, evenly distributed carbides that increase wear resistance. S600 is hardened and cryogenically treated to achieve an exceptional hardness of 64 HRC. This provides high wear resistance and good edge retention. Manufactured in the Austrian steel mill Böhler-Uddeholm.
Blade - a precisely designed Drop Point blade that offers the versatility needed for outdoor activities. Flat grind ensures controlled and efficient cutting, whether you are chopping wood, cutting through fabric or performing small, precise tasks. The use of Böhler S600 steel, known for its exceptional wear resistance, combined with cryogenic heat treatment, results in a blade with impressive hardness and durability. The EXP DARK coating increases corrosion resistance and maintains a low optical profile – ideal for tactical applications. The blade has been optimized for users who expect reliability in every situation, from everyday use to specialized field operations.
Handle - G10 grips - a material with high mechanical resistance that retains its performance even in extreme conditions. The knife fits comfortably in your hand, regardless of the conditions, ensuring a secure, safe grip with gloves or bare hands. The new, refined shape of the handle supports various knife handling techniques and reduces hand fatigue during prolonged use. The lanyard hole increases customization and security options, and the whole is rigidly connected to the blade in a full tang construction, guaranteeing the highest level of reliability.
Sheath - made of Cordura, equipped with a MOLLE system and a waist belt, allows quick access to the knife and flexible mounting depending on user preferences. It is a complete tactical set, prepared for operation in the most demanding environments.
