Oknife U1Ultra-Stealth – 2.36" Zirconium Oxide Ceramic Folding Utility Knife
The Oknife U1Ultra-Stealth is a premium folding utility knife built around a 2.36" zirconium oxide ceramic blade, a stealth grey OAL™ super aluminum handle, and versatile button-lock, thumb-stud, and flipper deployment. The Oknife U1Ultra-Stealth pairs razor-sharp ceramic cutting performance with a lightweight, corrosion-proof build for everyday carry.
The ceramic blade is rated at 1200HV+ hardness for exceptional long-term edge retention, resists rust and staining, and stays sharp far longer than typical steel utility blades. A standard trapezoidal blade shape with an 11°–18° edge supports slicing, piercing, and detailed cutting, while the anti-slip textured aluminum handle and titanium-coated stainless clip make the Oknife U1Ultra-Stealth easy to grip and carry.
