Premium titanium construction. A replaceable ceramic blade. Everyday utility with a little extra polish.

The OKNIFE U1 Ultra Titanium brings a refined approach to the everyday utility knife, combining a TC4 titanium handle, replaceable zirconia ceramic blade, and smooth folding action in a compact, pocket-friendly design.

The titanium handle features a subtle, matte finish created through a 400-grit surface treatment, offering excellent corrosion resistance and a comfortable grip. A brushed stainless steel blade holder complements the understated appearance, while textured spine jimping provides additional control during cutting.

At the heart of the U1 Ultra is a replaceable white zirconia ceramic utility blade. With a manufacturer-rated hardness of 1200 HV and an 18° edge angle, the blade offers excellent edge retention for everyday cutting tasks. Its ceramic construction resists corrosion and staining, while a specialized brushed surface treatment is designed to reduce cutting friction and make cleaning easier.

Unlike traditional sliding utility knives, the U1 Ultra uses a screw-secured blade holder to minimize blade movement and provide stable, controlled cutting. The design exposes up to 85% of the blade's usable cutting edge, making efficient use of the replaceable blade.

Three convenient opening methods—a flipper tab, thumb stud, and button-operated mechanism—give you options for accessing the blade, while precision ceramic bearings keep deployment smooth.

A deep-carry pocket clip completes the package, making the U1 Ultra an appealing choice for everyday carry, office tasks, workshop projects, and anyone who appreciates a well-made cutting tool.

Why We Like It

We've handled plenty of utility knives.

Most of them are perfectly happy being practical, inexpensive, and utterly unremarkable.

The U1 Ultra apparently didn't get that memo.

Titanium handle? Check. Ceramic blade? Check. Smooth bearings and multiple opening options? Also check.

It's a utility knife for someone who appreciates good materials and thoughtful engineering, even when the job is simply opening another delivery.

And we particularly like the replaceable ceramic blade. You get the edge retention benefits of ceramic without committing to an entire new knife when the blade eventually needs replacing.

Practical? Absolutely.

A little luxurious for a box cutter?

Also absolutely.

Premium TC4 Titanium Construction

The U1 Ultra features a precision-machined TC4 titanium handle with a matte surface finish.

Titanium provides an excellent combination of corrosion resistance, strength, and comfortable everyday carry, while the brushed stainless steel blade holder adds durability and a clean, understated appearance.
