Olight Oknife Otacle U1 Ultra Navy Blue Folding Utility Knife with Ceramic Blade - OAL Aluminum Alloy​

Elevating EDC Excellence with OAL Aluminum Alloy​
The U1 Ultra Pocket Folding Utility Knife carries forward the legacy of its predecessor, the U1 Utility Knife, boasting tried-and-true strengths: smooth and stable blade deployment, a screw-secured blade system for reliable performance, and an impressive 85% blade utilization rate—minimizing waste while maximizing value. Designed for universal accessibility, it features three intuitive opening methods: a quick-release fin for one-handed speed, a thumb stud for controlled single-hand operation, and a button lock for secure, instant access. Whether you’re a beginner or a seasoned pro, young or seasoned, this pocket knife is engineered to be instantly familiar and effortlessly mastered.

​Premium OAL Aluminum Alloy Handle: Strength Meets Style​
The U1 Ultra now introduces an OAL (O-Aluminum) super aluminum alloy handle, engineered to match the comprehensive performance of TC4 titanium alloy. Through advanced oxidation treatment, the handle develops an ultra-hard, thick oxide layer, delivering exceptional wear resistance while preserving vivid, clear color and texture—ensuring long-lasting aesthetics even with frequent use. Paired with a stainless steel frame finished in sleek black titanium plating, and complemented by a pristine white ceramic blade, the U1 Ultra strikes a harmonious balance of refined texture, premium tactile feel, and striking visual appeal.

​Innovative Ceramic Blade: Performance Redefined​
At the heart of the U1 Ultra lies its groundbreaking ceramic blade, combining practicality with precision. Beyond its inherent corrosion resistance and non-conductive properties, the blade excels in cutting performance, stain resistance, and aesthetic appeal. With an 18° edge angle, it achieves razor-sharpness for effortless slicing, piercing, and detailed tasks. Crafted from 1200 HV zirconia ceramic, the blade retains its edge up to 10x longer than stainless steel, ensuring enduring sharpness in demanding applications.

The blade’s specialized brushed finish elevates its utility further: reducing friction for smoother cuts, minimizing dirt adhesion for easy cleaning, and enhancing visual depth with subtle, high-end texture. This fusion of durability, hygiene, and style sets a new benchmark for ceramic blade technology.

​Your Next EDC Essential​
Combining a robust OAL aluminum alloy handle, a high-performance ceramic blade, and a market-proven screw-fixed blade replacement system, the U1 Ultra delivers a pocket knife that excels in both form and function. Lightweight, compact, and visually striking, it redefines what a modern EDC tool should be—combining innovation, reliability, and elegance into one indispensable companion.
