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.

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, that dares to be 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 is committed to high quality workmanship and an innovative approach to design. This has been recognised by, among others, the legendary American brand Microtech, which for the first time in its history commissioned products designed by it to be made outside the USA, precisely by the Chinese company Rikeknife. These include the SOCOM Bravo and Anax folders and Kyroh Pen tactical pens.
Damascus - Damascus stainless steel blade with a unique pattern. A blade consisting of two different types of steel forged and folded together in different ways to obtain this amazing pattern. It is characterised by a high hardness of 58-60 HRC.
Blade - Persian type, finished with an etching highlighting the unique damascus patterns. The long cutting edge converges towards the needle-sharp tip of the knife. The thickness of the blade and the high, flat grind give excellent cutting edge geometry and extreme cutting performance. Ball bearing ceramic supports the opening of the blade with a quick flipper flipper (index-finger flipper) acting as a stag once opened. We can also open it by means of a hole in the wedge. The Blade overlay is an extension of the Handle pattern and provides a thumb rest for better control of the knife. The whole is locked with a modern Frame Lock.
Handle - monolithic, made from a single piece of 6AL4V titanium milled with 3D CNC machine tools. This provides incredible strength, but requires the highest level of skill and precision in production. The chamfered cover edges and fore finger groove eliminate sharp edges and improve grip ergonomics. On the back of the Handle, stylised circles which, with holes milled below, bring to mind a section of Alien's skeleton. The pivot is decorated with the stylised Rike Knife brand logo. The single-position (right) deep carry clip allows the knife to be carried discreetly in the pocket in the tip-up position (blade tip up).
Carrying case - the knife is packaged in a zippered nylon soft pouch with the brand logo for safe carrying and storage of the folder.
