From Dull to Razor Sharp in Minutes
See how a dull blade fails to cut through a simple sheet of paper.
A few rolls with OKNIV and your knife is sharp again.
Smooth, precise cuts—ready for any kitchen task.
Get razor-sharp results in just a few easy steps:
1. Choose the Right Angle
Identify the correct sharpening angle for your knife—typically 20° for Western blades or 15° for Japanese styles. Not sure? A quick online search can help based on your knife type.
2. Position the Blade Securely
Attach your knife to the magnetic guide. This holds the blade firmly in place for consistent, safe sharpening.
3. Begin Sharpening
Start with the coarse 400-grit disc. Sharpen one side with smooth rolling motions, then flip the blade and repeat on the other side.
4. Refine the Edge
Switch to the fine 1000-grit disc and lightly polish the first side for a clean, finished edge.
5. You're Done!
Your knife is now sharper, safer, and ready for action.
Precision Meets Tradition
Rooted in Japanese craftsmanship, the OKNIV Rolling Sharpener combines precision design with high-quality materials to deliver effortless, long-lasting sharpness—every time you roll.
It depends on the condition of your blade and the type of steel. But with OKNIV, you’ll typically get your knife razor-sharp in just 5-7 minutes. After that, keeping it sharp only takes a few quick rolls.
No worries. If you’re working with a larger blade, just place your OKNIV sharpener on a raised surface like a thick cutting board. This adjustment helps align the blade with the sharpening disc perfectly.
Our sharpening discs are crafted with industrial-grade diamond, one of the most durable materials available. When used properly, OKNIV discs provide long-lasting performance and won’t need frequent replacing. The diamond-coated discs deliver reliable sharpening results, while the ceramic discs are designed to refine and polish the blade for a superior edge. However, with regular use, both the diamond and ceramic discs will eventually wear down over time and should be replaced to maintain optimal sharpening performance.
OKNIV is compatible with most standard kitchen knives, cleavers, hunting knives with smooth edges, and folding knives. However, it is not designed for serrated blades or scissors, as these require a different sharpening approach.
A 20° angle offers durability and is best for Western knives, which often have softer steel. A 15° angle provides a sharper, more precise edge, ideal for harder Japanese blades. However, sharpening at a lower angle might require more frequent touch-ups and can remove more metal over time.
Best knife sharpener I have used to date.
Good product, used in my own restaurant by my chefs they likes it a lot. Words they gave me were it's easy to user and handling is simple . It works the way it should as we had to pay certain amount to a company before weekly for knife shaping we can save that money now. Thanks
