The Original That Changed the Game

How it worksEffortlessly sharpen like a pro

Simply attach your knife to the magnetic holder, select from preset edge angles (15° or 20°), and roll. No guesswork, just results!
  • Attach knife to magnetic holder

  • Roll Tumbler sharpener along the blade

  • Slice with ease & enjoy your sharp knife

    DIAMOND SHARPENING DISC

    Strips back the edge. Fast.

    Diamond is the hardest natural material on Earth — and that’s exactly why it works.
    This disc removes the first layer of your knife’s edge fast, getting it back into proper shape with zero fuss. No water. No soaking. Just straight to the point.

    FINE HONING DISC

    Refines the edge. Finishes the job.

    Once the diamond disc has done the heavy lifting, this disc steps in to smooth things out. It cleans up any burrs or leftover roughness — so your edge isn’t just sharp, it’s clean and precise.

    2 SHARPENING ANGLES

    One sharpener. Two ways to get it right.

    Whether it’s your everyday kitchen knife or that fancy chef’s knife you got as a gift — this sharpener’s got you covered.

    Not sure what angle you need?
    Start with 20° — it suits most knives found In the United States kitchens.

    Got a thinner or more delicate blade?
    Drop it down to 15° or 20° for a sharper, cleaner edge.

    With two angles to choose from, you don’t need to know all the knife jargon — just set it, roll it, and get that edge razor sharp.

    • The sharpened knife is very sharp

      One of those rare "internet products" that genuinely does what it

      claims.

    • Great sharpening stone

      I looked at other rolling sharpeners but none of them offer the versatility that this one does. If you have speciality knives that have to be sharpened to certain angles this is the perfect choice!

    • Super, Recommended

      Product came earlier than expected, good cuality materials and works perfect.

    • Got it late but still Impressed

      Delivery was late, But 100% worth the wait.
      Of all the sets on the market, This roller sharpener seems to be the most versatile.

    • Whetstone

      Sharpening knives has always been a chore that I avoided. Makes it super easy to get it over with and move on with my day! I sharpened all my knives in 1 sitting and now I just keep them maintained.

      Karen B.

    • Very good quality

      As a chef, I have to keep my knives sharp and time is money. The quicker I can get my blades right the better. Having multiple grit options is a must so I can re-shape an edge quickly before polishing.
