About this item

  • Precise & Long-Lasting Sharpness: Any serious chef knows quality knives are expensive. Keep yours cutting like new for much, much longer with a Tumbler rolling knife sharpener. With our easy-to-use system, anyone can get factory-sharp knives in minutes.
  • Powered by Diamonds: The sharpening disc is plated with nature's hardest, most-effective sharpening stones: diamonds. The D35 grit size (compare with 800 whetstone grit) effortlessly removes the first layer of your knife’s edge while restoring sharpness.
  • A Finer Edge: A proprietary stainless steel helix disc on the other end of the kitchen knife sharpener removes the burr of your knife’s edge after the base sharpening. The result? A finer edge for more precise cutting that makes all kitchen tasks easier.
  • Simple, But Effective: The Tumbler knife sharpening kit is deceptively simple, but also surprisingly functional. Simply choose your angle and use the magnetic knife holder to secure your blade. Then, roll the sharpening disc back and forth until sharp. Finally, flip Tumbler over and hone the edge using the stainless steel disc.
  • 15 & 20 Degree Angle Sharpening: Easily & quickly sharpen traditional and specialty blades. Powerful magnets keep your knife at exactly 20° or 15°, so you'll always get uniform angles over the entire cutting edge.

★★★★★

Easy to sharpen even cheap knives with it.

NickDecember 11, 2025

This thing works great. It may take a bit more time than you might think the first time you sharpen your knives with it, but it is super easy to keep them sharp once you get that edge. It can be a bit tricky on fillet knives or paring knives due to the magnet thickness, but it's overall a fantastic tool. Super easy to use and it takes the guesswork out of sharpening angles.

Works great to sharpen knives

luvfor775January 6, 2026

This was a Christmas gift for my husband and he immediately used it to sharpen our dull knives. It was impressive to say the least. It sharpened the knives quickly, easily, and it is light weight and portable so he can take it to my elderly dad's house to sharpen his knives. Great product. Read more

Simple to SHARP!

Mark RenfroDecember 24, 2025

The Tumbler certainly is helping to revive the sharpness of our knives. We will be working on them over the next bit. Simple process with good results. Give it a try! Read more

Easiest Home Knife Sharpening!

M. NoonanDecember 27, 2025

I have never attempted to sharpen my own knives before. I have some older Henckles and some newer Wustof that needed to be sharpened, but I didn’t have any place here to get it done. I just used the knife sharpener today and was so pleased with the ease of use and the results. My knives are sharp against! I don’t like complicated instructions, so this is perfect because it is so easy and quick. It will definitely make it easier to have sharp knives without traveling to someone and paying more than the cost of the sharpener for one set of knives to be sharpened. I recommend this wholeheartedly! Merry Christmas to me! Read more

★★★☆☆

It didn’t work for my applications

Gerald HendersonOctober 22, 2025

I returned the Original Tumbler Rolling Knife Sharpener because it didn’t live up to the hype. A lot of reviews indicated it was a good tool, but for my intended use it wasn’t appropriate. For smaller knives it was almost impossible to use correctly. For larger knives like a chef’s knife it’s okay. It definitely doesn’t work like a good stone. I tried it on several different metal blades but never got the sharpness described in the ads/brochures. In my opinion because of its limitations I think it’s way overpriced. A good stone is a fraction of the price and can be used across different blade sizes, shapes, and steels. Unfortunately I can’t recommend the Original Tumbler Rolling Knife Sharpener. Read more
