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.
WeKnife Brr15 Gray Titanium/Jungle Wear Fat Carbon, Hand Rubbed Satin is an exclusive interpretation of Rafal Brzeski's design, created by WeKnife as a combination of refined design and advanced EDC functionality. The design is based on balanced form, perfect proportions and precise manufacturing craftsmanship, offering high performance culture and high-end aesthetics. Blade is made of Böhler M390 powder steel , considered one of the best materials in utility knives thanks to its exceptional abrasion resistance, excellent sharpness retention and very high corrosion resistance. The Wharncliffe profile provides full control of the line of cut throughout the entire range of the blade, allowing precise maneuvering in EDC tasks. The hand satin finish emphasizes the exclusivity of this version. Handle made of milled 6Al-4V titanium and Jungle Wear Fat Carbon inlays , creating a highly resistant yet decorative structure with a unique pattern. The profiled edges provide a stable grip, while the ergonomic shape of the handle guarantees full control and comfort during daily use. The bolster lock has been integrated into the titanium frame, offering stability and the discreet elegance of security. The front flipper type opening mechanism , supported by ceramic bearings, allows the blade to be unfolded smoothly and instantly with one hand. The functionality of the design is complemented by a titanium deep-carry clip and a solid backspacer, increasing the rigidity of the entire body. The WE24007-3 is the perfect choice for collectors, enthusiasts of modern design and discerning EDC users who appreciate uncompromising build quality.
Rafal “Brrr...” Brzeski - excellent Polish knifemaker whose knives sell perfectly all over the world. His motto is "I try to make each of my knives fully functional and practical, but distinguished by details that you won't find in any mass production. The devil is in the details.".
M390 - a martensitic high-performance chrome steel produced by powder metallurgy. Due to its 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, subjected to vacuum and cryogenic treatments 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 - made of Böhler M390 powder steel , offering maximum blade durability, exceptional abrasion resistance and high working edge stability in long-term EDC use. The Wharncliffe profile provides a flat cutting edge, allowing full cutting control along the entire length of the blade - especially for precise, flat cuts along the surface of the material. The surface of the blade has been hand-finished with a satin finish. The flat grind (flat grind ) facilitates smooth entry into the material and allows efficient distribution of cutting power in everyday tasks. Blade is smoothly operated thanks to the front flipper and ceramic ball bearings. Safety is provided by the bolster lock mechanism , which ensures that the blade is securely locked in the open position.
Handle - made of milled titanium 6Al-4V with decorative inlays of Jungle Wear Fat Carbon, creates a lightweight, stable construction with high resistance to mechanical damage and premium aesthetic character. Each carbon fiber inlay generates a unique pattern layout, giving an individual character to each piece. Delicate chamfers and ergonomic curves improve comfort and provide a secure grip during intensive work. The integrated bolster lock maintains a clean design line. The entire design is complemented by a titanium deep-carry (tip-up) clip for discreet carrying and a solid backspacer, increasing the mechanical stability of the Handle. The design combines the highest utility class with perfect aesthetics and excellent mechanism culture.
