The Original Tumbler Rolling Knife Sharpener™ - Knife Sharpening Made Easy - Knife Sharpener Tool for Kitchen, Outdoor & Utility Knives - Kit Offers 15 & 20° Angles - Kitchen Gadgets & Gifts for Him

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.

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.

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!

I bought this over a year ago, still working great! My 14 year old has sharpened many knives, turn out sharp enough to cut hair.

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!

It has been great to use so far. Completely revived some old knives I had. Easy to use and takes just seconds.

Easy to use and works amazing.

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.
