Kubey knife Jaw KU440E Karambit Style Linerlock Folding Knife – Transparent Ultem Handle 2.52” Blackwash 14C28N Pikal EDC Pocket Knife with Caged Ceramic Ball Bearings
Karambit-shaped EDC folders are beloved for their superior cutting control, and the Kubey Jaw KU440E upgrades this classic tactical layout with premium transparent Ultem handles and high-performance steel. Designed by MUZI Design and fully manufactured in China, this ambidextrous linerlock folding knife comes with Kubey’s lifetime warranty, built to handle daily utility work and outdoor adventures with lasting reliability.
The knife’s core performance comes from its 2.52-inch Pikal blade crafted from marine-grade 14C28N stainless steel. After precise vacuum and cryogenic heat treatment, the blade reaches a balanced HRC hardness of 60–62, delivering impressive edge retention and outstanding rust resistance. The scratch-concealing blackwash finish adds a rugged tactical look, while its flat ground plain edge sharpened at a 15°–20° angle provides clean piercing and slicing power for all daily cutting tasks. At only 3.1 mm thick, the blade maintains structural strength without extra weight, and the whole knife weighs just 126 grams for fatigue-free all-day pocket carry.
What sets this model apart from standard karambit folders is its eye-catching transparent Ultem handle. Stretching 4.88 inches long and 1.3 cm thick, the textured Ultem scales offer a steady non-slip grip that works perfectly for both left and right-handed users. A built-in black PVD stainless steel finger ring locks your hand securely during heavy cutting, the signature functional advantage of karambit designs. Caged ceramic ball bearings under the handle enable ultra-smooth, responsive one-handed opening, supported by a solid stainless steel liner lock that eliminates blade wobble while open.
Every metal hardware component, including reversible tip-up pocket clip, pivot cap, backspacer, screws and filler tab, is coated with durable black PVD to resist corrosion. The ambidextrous clip supports left or right pocket carry for flexible daily transport. When fully opened, the knife measures 7.4 inches overall, striking a smart balance between compact portability and functional cutting length.
Combining unique translucent Ultem aesthetics, reliable 14C28N steel and silky bearing deployment, the Kubey Jaw KU440E is a standout tactical EDC choice for knife collectors and everyday carriers alike.
