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 RK 1902 R/CF Titanium/Red Carbon Fiber, Bead Blasted from Rike Knife is an advanced EDC folder that combines precision craftsmanship, innovative design and modern aesthetics. The design was developed for users who expect excellent performance culture and reliability in all conditions - both urban and off-road. The milled titanium skeleton provides adequate stiffness and resistance while keeping the weight low, which translates into comfort in carrying and handling. Blade made of Böhler M390 powder steel, known for its hardness, abrasion resistance and long-term sharpness retention, is responsible for cutting performance. The modified drop point profile and full flat grind promote precise cutting performance, while the bead blasted surface gives the overall blade a matte, utilitarian feel, nullifying unwanted light reflections. The Handle is based on a hybrid system - titanium elements are complemented by Red Carbon Fiber inlays , which not only enhance the aesthetics of the model, but also increase grip. The design includes a frame lock with a hardened steel inlay, a deep carry clip and a backspacer with a rope hole, which ensures full functionality in everyday use and in demanding conditions.
Rike Knife - an independent brand founded by long-time knife enthusiast Richard Wu. With a background in mechanical design and manufacturing, he constantly strives for excellence and perfection, helped by his professional design team and his own independent factory. RikeKnife is an unconventional brand, grounded in original design, which has the courage to become an innovator and challenge the traditional solutions used by contemporary knife companies. It uses only the highest quality materials to produce knives of excellent quality for customers around the world. Enjoying a well-deserved reputation in the world of knives, the brand relies on high quality workmanship and an innovative approach to design. This was appreciated, among others, by the legendary American brand Microtech, which, for the first time in its history, commissioned its designed products to be made outside the US, precisely by the Chinese company Rikeknife. These include SOCOM Bravo and Anax folders and Kyroh Pen tactical pens .
M390 - a martensitic high-performance chromium 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), and is hardened between 59-61 HRC. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - with a modified drop point profile is made of advanced M390 steel, guaranteeing exceptional edge durability and wear resistance. The flat grind promotes a smooth cut, while the bead blasted finish reduces glare and protects the surface from minor scratches. The precision-shaped tip allows for controlled piercing and maneuvering of the blade. A hole in the Blade acts as a thumb rest, supporting quick one-handed opening. The whole is based on ball bearings, which ensures smooth and dynamic operation of the blade. Frame lock with steel inlay protects the mechanism from wear and increases its durability.
Handle - milled titanium frame gives the construction high resistance to deformation and excellent stability with low weight. Red Carbon Fiber inlays introduce not only an aesthetic accent, but also improve the grip, especially in situations requiring precise handling. The overall design has been contoured for ergonomics - chamfered edges and finger undercuts increase comfort. The use of a frame lock with a hardened inlay ensures safe use, while a deep carry clip and a backspacer with a cord hole enhance functionality for everyday carry. Anodized elements near the pivot and screws complete the look, adding a distinct technical character.
