LionSteel L.E.One Mid Karambit Knife Black Aluminium, Black M390 by Emerson Design (LE2 A BB)

LionSteel L.E.One Mid Karambit Black Aluminum, Black M390 by Emerson Design (LE2 A BB) is a compact folding karambit with a black M390 blade and the Emerson Wave system.

LionSteel L.E.One Mid – black karambit with the Emerson Wave system

LionSteel L.E.One Mid Karambit Black Aluminum, Black M390 by Emerson Design (LE2 A BB) is a compact version of the L.E.One folding karambit, created by lionSTEEL in collaboration with Emerson Design. The model combines a sickle-shaped blade, a finger ring, a Frame Lock locking mechanism, and the Emerson Wave system, which allows the blade to open quickly when drawing the knife from a pocket. The Mid version retains the technical character of the larger model but offers a smaller profile and more comfortable everyday carry.

The blade, made of Böhler M390 steel, with a Hawkbill / Karambit profile, Flat Grind edge, and Black PVD finish, creates a configuration with a distinctly tactical, mission-oriented character. The handle, made of Aluminium Ergal in Black, utilizes Solid® Knife monolithic technology, and opening via the Emerson Wave, flipper, or thumb hole provides the user with several practical handling options.

Böhler M390 – premium steel in a Black PVD finish

Böhler M390 is a powder steel valued for its high wear resistance, good corrosion resistance, and long-lasting sharpness. In the compact L.E.One Mid karambit, this material performs well for fast, controlled cutting of ropes, straps, belts, packaging, and fibrous materials.

The Black PVD finish gives the blade a uniform, technical look and enhances the knife’s tactical aesthetic. Combined with a black Ergal aluminum handle, this creates the most discreet and visually aggressive version of the L.E.One Mid, while retaining the full functionality of the Emerson Design construction.

Hawkbill / Karambit and Flat Grind – Curved Cutting Geometry

The Hawkbill / Karambit profile features a strongly curved edge line that guides the material toward the blade and increases cutting efficiency. This geometry works well with ropes, straps, belts, and fibrous materials, while also giving the knife the recognizable character of a karambit.

The Flat Grind facilitates smooth blade glide through the material, maintaining a good balance between cutting sharpness and edge durability. The serrations on the blade spine improve thumb control, and the Emerson Wave system allows you to quickly prepare the blade for use when opening the folder.

Black Aluminum Ergal and Frame Lock – Solid® Knife monolithic construction

The handle is made of Aluminum Ergal using Solid® Knife technology, meaning it is machined from a single block of material using precision CNC machining. This construction increases rigidity, reduces the number of components, and keeps the weight low. The Black color emphasizes the knife’s tactical character and creates a cohesive whole with the Black PVD blade.

The Frame Lock stabilizes the blade when open, and a steel inlay protects the lock surface from wear. The reversible Right / Left, Tip-Up clip allows you to customize carrying to your preferences, while the finger ring increases grip retention and facilitates control of the knife.

Emerson Wave, flipper, and thumb hole – quick access to the blade

The L.E.One Mid offers three practical ways to open the blade. The Emerson Wave allows you to open the blade as you remove the knife from your pocket, the flipper enables quick manual deployment, and the thumb hole provides an additional access point to the blade. This design enhances the folder’s functionality in various usage conditions.

The pivot mechanism, based on ball bearings, ensures smooth blade operation and fast, controlled opening. Combined with the Frame Lock and the monolithic Solid® Knife handle, this results in a compact karambit with an exceptionally technical design.

Technical data

Frequently Asked Questions

How does the L.E.One Mid differ from the larger L.E.One?

The L.E.One Mid is a more compact and lighter version of the L.E.One karambit. It retains the Emerson Wave system, finger ring, Frame Lock, and Solid® Knife construction, but features a shorter blade and smaller overall dimensions.

How do I care for and sharpen Böhler M390 steel?

Böhler M390 steel should be cleaned, dried, and periodically coated with a thin layer of oil after use. For sharpening, a diamond or CBN system works best when used with a steady hand and without excessive pressure.

What is the Emerson Wave used for?

The Emerson Wave is a hook on the blade that can catch on the edge of a pocket when drawing the knife. This allows you to quickly open the blade while removing the folder.

What makes the Hawkbill / Karambit profile unique?

The Hawkbill / Karambit has a curved edge that guides the material toward the blade. This geometry works well for cutting ropes, straps, belts, and fibrous materials.

What is Solid® Knife technology?

Solid® Knife refers to a handle milled from a single block of aluminum. This solution increases the structure’s rigidity, reduces the number of components, and results in a lightweight, durable knife frame.
