Kubey Jaw Tanto KU439D Karambit EDC Folder: Tiffany Blue G10, 2.52” Blackwash 14C28N Tanto Blade with Ceramic Bearings & Liner Lock
Tactical karambit-style folding knives have long been favored by EDC fans for their superior control, and the Kubey Jaw Tanto KU439D reimagines this classic silhouette with modern materials and striking visual flair. Created by MUZI Design and manufactured in-house, this compact linerlock folder targets everyday users and outdoor lovers, with a lifetime warranty that guarantees long-term reliability.
What makes this model a standout carry piece is its specialized 2.52-inch Tanto Pikal blade. Forged from 14C28N stainless steel and refined with vacuum plus cryogenic heat treatment, the blade hits a stable HRC 60–62 hardness rating, balancing exceptional stain resistance and dependable edge retention. Its matte blackwash coating masks scuffs from daily use, while a flat ground plain edge sharpened between 15° and 20° delivers sharp piercing and slicing performance for packages, camping prep and general utility tasks. At only 3.1 mm thick, the blade maintains structural rigidity without adding extra weight—the complete knife weighs just 135 grams for all-day pocket comfort.
The signature Tiffany blue G10 handle elevates both aesthetics and function. Measuring 4.88 inches in length and 1.3 cm thick, it delivers textured, slip-resistant hold for both left and right-handed carriers. Integrated black PVD stainless steel finger ring anchors your hand during heavy cutting, the core tactical benefit of this karambit layout. Under the scales, caged ceramic ball bearings ensure silky, snappy opening every time, backed by a robust stainless steel liner lock that eliminates blade play during operation.
All hardware components, including reversible tip-up pocket clip, pivot cap, backspacer and fasteners, receive a tough black PVD finish to ward off oxidation. The ambidextrous clip supports left or right-side carry, letting you customize your daily setup freely. Opened fully, the knife stretches 7.4 inches, striking a perfect balance between compact portability and usable cutting surface.
From its eye-catching blue G10 scales to its rugged 14C28N Tanto blade, the Kubey Jaw Tanto KU439D merges tactical functionality, smooth mechanical action and head-turning design, making it a go-to choice for collectors and casual EDC users.
