Kubey Interflow Knife Black Frag Titanium, Satin M390 by James Lowe (KB294C)

Interflow Black Frag Titanium, Satin A strong EDC folder that combines precision workmanship and reliability in all conditions. Designed by James Lowe, it stands out for its exceptional ergonomics and durability. The titanium handle, decorated with the characteristic Frag Pattern, guarantees excellent grip and durability for years of intensive use. The blade is made of Böhler M390, considered to be one of the best knife steels, and is vacuum-hardened and ice-hardened, which makes it highly resistant and keeps it sharp for a long time. Thanks to a precise mechanism based on ball bearings, the knife opens smoothly and without resistance. Every detail has been perfected to provide the user with a reliable tool for everyday use.

Kubey - an independent brand and one of the largest manufacturers of high-quality knives at an excellent price! The company's motto is “An Edge Above the Rest”. Thanks to the use of fast CNC machine tools, milling machines, laser cutting and custom manual finishing, the brand focuses on high-quality workmanship and an innovative approach to design. Kubey is legendary for the durability and functionality of its knife tools, which will last for years!

M390 Microclean® - martensitic high-performance chrome steel produced using powder metallurgy. Due to the alloy concept, it is characterized by extremely high wear resistance and high corrosion resistance. Thanks to its high wear resistance, it retains its edge shape, keeping the blade sharp for a very long time (requires minimal maintenance). Another advantage is its resistance to “wire” formation during sharpening. Steel with a high chromium content of 20.0% (Cr) with an admixture of 1.9% carbon (C), 4.0% vanadium (V), hardened to 59-61 HRC. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.

Vacuum & Cryogenic - the steel undergoes a specialized heat treatment process involving two key stages. Vacuum Heat Treatment - the steel is hardened in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the strength and structural integrity of the steel. Cryogenic Treatment: After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation changes the residual austenite into martensite, significantly increasing the hardness, wear resistance and overall durability. Thanks to these advanced processes, the steel ensures exceptional performance, offering both razor-sharp edge retention and extraordinary blade durability.

Blade - Tanto Point type, finished with an elegant machine satin finish. A mixed grind has been used here, in the back part it is a high, concave grind for cutting and precision work, the so-called Hollow Ground Primary Bevel. In the front part, we have a high, flat grind to strengthen the tip, the Flat Ground. Ceramic ball bearings ensure smooth and easy operation and support the opening of the blade with a flipper or pin in the handle. Upper jimping on the back of the blade, a ribbed thumb rest. The locking mechanism is a robust frame lock with a steel inlay to prevent the lock face from wearing off.

Handle - milled titanium 6AL4V, beveled edges of the covers eliminate sharp edges. The characteristic texture of the handle imitating the surface of a fragmentation grenade (Frag Pattern) not only looks good, but also prevents the knife from slipping in the hand during use. The whole is screwed to a solid backspacer, also made of titanium. The pivot axis is decorated with a titanium cap (Pivot Cap) in a contrasting color. The single-position (right) titanium deep carry clip allows you to carry the knife discreetly in your pocket in a tip-up position (with the tip of the blade up).
