Place your knife flat on the magnetic angle guide. Then roll the Karvé sharpener along the blade from heel to tip — the diamond wheel does all the work. A few passes on each side and your knife is sharp. No skill, no mess, no fuss.

Yes, completely safe. The magnetic guide holds your knife at a fixed angle throughout — no awkward gripping, no risk of slipping. You never touch the blade directly. Just place, roll, and lift. Thousands of customers use it every day without any issues.

Completely. No skill, no technique, no mess. Place your knife on the magnetic guide, roll Karvé along the blade a few times, and you're done. Sharp in under 60 seconds — first time, every time. If you can roll a tin of beans, you can use Karvé.

Yes. Karvé works on virtually every kitchen knife with a smooth edge — chef's knives, carving knives, santoku, and more. The only exception is serrated blades like bread knives. If your knife has a straight edge, Karvé will sharpen it.

Karvé sharpens at both 15° and 20°. Not sure which to use? Go with 20° — it's the best all-round angle for everyday kitchen knives and lasts longer between sharpenings. Use 15° if you have high-quality Japanese or Damascus steel knives.

Most knives are sharp in under 60 seconds. A very dull knife may take 2–3 minutes. Once sharp, a quick 30-second touch-up every few weeks keeps the edge in perfect condition.

The embedded diamond abrasive is designed to last 1,000+ sharpenings under normal home use. That's years of daily use for most households.
