Common Questions
How Often Should You Sharpen Your Knives?
For peak performance, sharpen your knives every 4-6 weeks with regular use. If you feel resistance while cutting or notice your knife crushing instead of slicing tomatoes, it’s time for a quick touch-up!
Which Angle Should I Choose - 15° or 20°?
For everyday kitchen knives and tough cutting tasks, use the 20° angle. Opt for the 15° angle when working with precision tools or Japanese-style knives. Both angles provide excellent results—choose based on your knife type and cutting needs.
How Long Does It Take to Sharpen a Knife?
A regular maintenance sharpening takes about 1-2 minutes per knife. If your knife is very dull and hasn’t been sharpened in a while, the first session may take 3-5 minutes. After that, quick touch-ups keep your edge sharp.
Is This Suitable for Expensive Knives?
Absolutely! Our gentle rolling mechanism and precision angles make it safe for all knives, including premium Japanese steel and high-end European knives. The magnetic guide ensures consistent angles, protecting your blade while delivering professional-grade sharpness.
