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.
L.E.One (lionSTEEL-Emerson One) Green Aluminum, Stone Washed the most technically advanced folding karambit in the world! Lionsteel's patented technologies and unique Emerson Design! A unique folder from the Italian manufactory equipped with CPM MagnaCut steel blade, Emerson Wave hook and "ReF" technology flipper.
Emerson Knives have been serving the world's most elite special forces soldiers in all global conflicts and secret missions for more than 20 years. They have been carried by US Navy SEAL teams, Delta Force, Army Special Forces, Army Rangers, US Marines, CIA Special Activities Division and even the legendary British SAS. The Emerson CQC-7 knife, which was used in the manhunt that killed Osama Bin Laden, was sold at auction for $35,400, making it the most expensive and valuable production knife ever made.
Karambit - a type of knife that originated in Indonesia, with roots in Malaysia and the Philippines. It is characterized by a finger ring and sickle-shaped blade, which is characterized by tremendous cutting efficiency. Hawkbill mimics the way an eagle's claw or a tiger's claw rips through, piercing and cutting simultaneously. Used as a working knife and for defense.
CPM MagnaCut - Powdered stainless steel produced by the Crucible® Particle Metallurgy (CPM) process. High in vanadium, molybdenum and niobium, it guarantees accuracy and purity unmatched by more "conventional" steels. Designed and developed specifically for blade production by Larrin Thomas, it meets all the requirements of knife enthusiasts. With CPM, MagnaCut was able to create a steel that combines unique properties like no other knife steel. The result is a blade material that offers a remarkable balance of wear resistance, strength and corrosion resistance. There is no other steel on the world market today that offers a comparable combination of superior properties. This exceptional steel is produced at Crucible® Industries' American steel mills.
Blade - aggressive, Hawkbill type. The rounded shape of the blade is characterized by great efficiency and speed of cutting. Plain blade with reinforced tip and strongly curved edge for maximum cutting effects is finished with glare eliminating and scratch masking Stonewashed method. The ramp (Thumb jimping) thanks to which we can better control the knife smoothly transitions into the Emerson Wave quick-opening system, allowing us to instantly retrieve the knife with the blade already open. In addition, we can open the knife using the oval opening in the head or with the ReF technology flipper. The smoothness of the opening is ensured by the ball bearings used. The whole thing is locked with a proven and popular frame lock with a steel insert that protects against wiping the face of the lock.
Emerson Wave - located on the back of the blade, Ernest Emerson's patented hook allows you to quickly open the blade when removing the knife from the pocket by hooking the hook to the edge of the pocket. Thanks to Wave, any Emerson folder equipped with this solution is the fastest knife in the world when it comes to opening speed. It's also faster than an automatic knife, as it's ready to use once you grab it.
ReF - (Removable Flipper System) located on the underside of the blade, the projection / flipper flipper facilitates quick opening of the blade with one hand. It consists of a small lever (flipper) protruding beyond the back of the handle when the head is closed. Thanks to ReF technology, it is possible to unscrew the flipper and open the wedge using only the oval hole or the Wave hook.
Handle - in green color. Made with Solid® Knife technology, obtained from a single block of solid Ergal aluminum, machined in 4D. As a result, a lightweight, monolithic skeleton (body) of the highest strength was obtained, which is a solid structural element. The grip facings were CNC machined, obtaining a non-slip texture with excellent grip. A two-position left/right compact clip allows you to carry the knife in tip-up (tip up) position. The handle is finished with a finger ring (Back Ring). It prevents accidental release of the knife from the hand and also makes it easier to rotate the folder around the finger, allowing you to perform traditional techniques.
