Kubey Knife Stheno KU404E Amber Ultem Fixed Blade Karambit – Blackwash 14C28N Clip Point EDC Knife with Kydex Tek-Lok Sheath
If you are searching for a compact ring-handle fixed blade that merges distinctive karambit-inspired ergonomics, premium translucent aesthetics and dependable cutting power, the Kubey Stheno KU404E makes an outstanding addition to any EDC lineup. Created by MUZI Design, this ambidextrous full tang knife delivers tight, controllable slicing performance for urban chores and light outdoor tasks, fully protected by a comprehensive lifetime warranty against manufacturing defects.
At its core sits a 2.95-inch clip point blade crafted from trusted 14C28N stainless steel. Each blade undergoes professional vacuum and cryogenic heat treatment to reach HRC 60–62 hardness, offering reliable edge retention and excellent corrosion resistance for regular use in varying environments. The flat-ground plain edge is sharpened at a practical 15°–20° angle, ideal for precision slicing and piercing. Its moody blackwash finish conceals scuffs, fingerprints and daily wear, creating sharp visual contrast against the warm amber Ultem handle. With a thickness of 0.15 inches, the blade delivers solid rigidity without excessive mass.
The handle is constructed from textured amber Ultem, a high-performance polymer known for heat resistance and structural durability. The integrated finger ring locks your hand securely in position during cutting to prevent slippage, while grid patterning enhances grip even under damp conditions. Black PVD coated stainless steel screws firmly secure the Ultem scales to the full tang blade. The knife weighs only 3.07 oz (87 g), and the compact 4.29-inch overall length enables discrete carry.
Every Kubey Stheno KU404E comes supplied with a custom-molded black Kydex sheath equipped with a versatile Tek-Lok belt attachment. The sheath safely encapsulates the blade, and the adjustable mount allows vertical or horizontal carry on belts, packs and gear. The sheath itself weighs just 1.13 oz for minimal extra load.
Combining robust 14C28N steel, functional ring-handle geometry, eye-catching amber Ultem construction and flexible Kydex carry hardware, the Kubey Stheno KU404E is a unique compact fixed blade perfect for EDC enthusiasts and knife collectors seeking something outside standard folder designs.
