WeKnife Collinear Knife Black Titanium, Black Stonewashed M390 (WE22034D-1)

Collinear Black Titanium, Black Stonewashed is a design that consistently embodies the concept of a clean, geometric form subordinated to functionality. This model stands out with its distinctly linear silhouette, sharp breaks in the planes, and a minimalist approach to detail, creating a tool with a distinctly technological aesthetic. It is an EDC knife designed for users who value precision craftsmanship, structural integrity, and a modern design language. The blade, made of Böhler M390 steel, has been shaped into a reverse tanto profile and features a flat grind, which translates to high cutting control and increased functionality at the tip. This geometry enables effective performance both in tasks requiring greater force and in the more precise utility operations typical of EDC knives. The handle, made entirely of 6AL4V titanium, is an integral part of the construction, offering high rigidity and wear resistance. Its slender, elongated form is enhanced with functional milling that improves grip while maintaining a minimalist and cohesive aesthetic. The mechanism, based on ceramic ball bearings, ensures smooth, fast operation, and the frame lock mechanism guarantees safe use. Collinear is a model for users seeking a modern premium knife with an architectural form and high EDC functionality.

M390 - a high-performance martensitic chromium steel produced using powder metallurgy. Due to the alloy’s composition, it features exceptionally high wear resistance and high corrosion resistance. Thanks to its high wear resistance, it retains its edge shape well, allowing the blade to stay sharp for a very long time (requiring minimal maintenance). Another advantage is its resistance to “wire” formation during sharpening. Steel with a high chromium content of 20.0% (Cr), alloyed with 1.9% carbon (C) and 4.0% vanadium (V), hardened to a hardness range of 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—the reverse tanto profile defines the character of this design—a clearly defined spine line transitioning into an angular tip increases the strength of the blade tip and improves control during precision work. This type of geometry allows for effective manipulation of the tip and better force transfer during cutting. The flat grind used ensures excellent material penetration and smooth cutting while maintaining adequate cutting edge strength. This geometry supports versatile utility—from everyday EDC tasks to more demanding technical work. The black stonewashed finish reduces the visibility of micro-scratches and increases the surface’s resistance to wear and tear, while giving the blade a raw, technical character. The overall design maintains visual consistency with the minimalist concept. Safety is ensured by the frame lock, which provides stable and secure blade locking during use and high structural load resistance.

Handle - made of 6AL4V titanium, it forms a monolithic and durable base for the entire construction, ensuring high mechanical resistance and long-term durability under intensive use. This material also guarantees a favorable strength-to-weight ratio, which translates to comfort during everyday carry. Distinctive, longitudinal milling along the handle increases grip and improves control, especially during tasks requiring greater precision. The slim profile promotes a natural hand position and comfort of use, both in a standard grip and in more technical grips. This is complemented by a titanium clip in a tip-up configuration, which allows for stable and discreet carrying of the knife in a pocket. The result is a refined design with a distinctly technological aesthetic, meeting the demands of users in the premium segment.
