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.

Excentric Black Titanium, Bead Blasted is a work of applied art that combines engineering precision with premium aesthetics. Designed as a result of a collaboration between esteemed designer Gregory “Kombou” Grabarski and Toni Tietzel of TNT Knives, it is a perfect example of a modern approach to folding knives. The blade of impressive length is made of exceptional Böhler M390 steel, valued for its resistance to corrosion and retention of sharpness even under heavy use. The handle, made of milled titanium, not only impresses with its details, but also provides comfort thanks to its ergonomic shape. The subtly balanced weight makes the knife fit perfectly in the hand, guaranteeing full control. The folding mechanism works smoothly and without resistance, highlighting the reliability of the design. Excentric is an excellent choice for those who value functionality, durability and sublime elegance.

His pursuit of perfection and passion for combining creativity with technology make each knife from his workshop both a functional tool and a unique work of art.
M390 - a martensitic high-performance chrome steel produced by powder metallurgy. Due to the alloy concept, it has extremely high wear resistance and high corrosion resistance. Due to its high wear resistance, it adequately maintains the shape of the edge, so the blade stays sharp for a very long time (requiring minimal maintenance). Another of the advantages is resistance to the formation of “wire” during sharpening. The steel has a high chromium content of 20.0% (Cr) doped with 1.9% carbon (C), vanadium 4.0% (V), hardened between 59-61 HRC, vacuum and cryogenic treatment and double tempering. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade- Wharnto type, (a mix of Wharncliffe and Tanto), with a striking Bead Blasted finish. The wide blade converges toward the needle-sharp tip of the knife. A mixed grind is used here, in the rear part is a high, hollow grind for cutting and precision work, the so-called Hollow Ground Primary Bevel. In the front part, we have a high, flat ground to strengthen the Flat Ground tip. To improve piercing capabilities, an unsharpened false blade is brought out in the upper part. Ball bearing ceramic supports the opening of the blade with a fast flipper flipper. When opened, the flipper forms a mini-guard to prevent the hand from slipping on the blade. The entire blade is locked with a modern Frame Lock with a steel inlay to prevent wiping of the lock face.
Handle - made of milled titanium 6AL4V, beveled edges of the covers eliminate sharp edges. The whole bolted to a solid backspacer, also made of titanium. The pivot axis is decorated with a bolster made of titanium in a contrasting color. A fore finger groove improves grip security. A single-position (right) titanium deep-carry clip allows you to carry the knife discreetly in your pocket in tip-up (blade tip up) position.
Case - included zippered soft nylon case with manufacturer's logo for safe storage and transportation of the folder.
