KB KNIVES Coeus KB286E Frame Lock Folder – DLC Diamond Milled Titanium Spear Point M390 Tactical EDC Knife Full Breakdown
For EDC collectors and tactical enthusiasts hunting a compact, premium all-titanium folder with elite blade steel, the KB Coeus KB286E stands out as a refined daily carry solution. Developed in-house by the Kubey Knife Team and manufactured in China, this frame lock knife is backed by a lifetime warranty, engineered to balance sharp cutting performance, lightweight portability, and rugged tactical styling with ambidextrous geometry for all users.
At its core sits a Bohler M390 spear point blade, one of the most sought-after premium stainless steels for its unmatched edge retention and corrosion resistance. Each blade undergoes strict vacuum and cryogenic heat treatment to hit a HRC 60–62 hardness rating, with a flat grind factory sharpened to a 15°–20° plain cutting edge for clean slicing across daily tasks and light tactical work. A full black DLC finish coats the entire blade, resisting fingerprints, scratches, and surface wear for long-term everyday use. The blade measures 3.11 inches, with a total open length of 7.28 inches, while the knife weighs only 3.35 oz (95 g) — significantly lighter than many comparable titanium tactical folders.
The handle construction delivers both grip and premium aesthetics. Machined from solid titanium, the scales feature deep diamond milling texture to deliver non-slip control even with wet or gloved hands, finished in matching DLC black coating for a unified stealth look. With a slim 0.47-inch handle thickness, the Coeus slides seamlessly into jeans, cargo pockets, or tactical bags without bulky protrusion. Beneath the handle, a robust titanium frame lock pairs with caged ceramic ball bearings, creating buttery-smooth, zero-wobble blade opening every time you draw the knife.
Every hardware component uses identical DLC-coated titanium: backspacer, pocket clip, pivot cap, and all assembly screws share the same scratch-resistant finish. The low-profile titanium clip supports tip-up right-side carry only, keeping the knife securely anchored while maintaining a streamlined silhouette.
Combining top-tier M390 steel, fully titanium DLC construction, ultra-light weight, and tactical-ready design, the KB Coeus KB286E is a versatile upgrade for anyone prioritizing performance and durability in their daily carry rotation.
