The device is a little smaller than I had expected, but it works fairly well on larger knives. The block is about 3/4 inch, so if your knife blade is less that the block, it won't work. The magnets on the block hold the knife well and the block is easy to hold into place as you roll the grit cylinder back and forth. Over all, I find it worth the money. Read more

Drop any preconceived notions by the way this product looks. It work incredibly well. I have expensive Japanese wet stones for my best cutlery yet this product does as good or better. And much easier, just a few swipes. Read more

I purchased the Knife Sharpener Tool Rolling Knife Sharpener Kit as a suggestion from my daughter, and I couldn’t be happier with it! We often have family dinners, and one night, while preparing a meal, I reached for a knife only to realize how dull it had become. My daughter, a sous chef, showed me how to use this sharpener, and I was amazed at how easy it was. This sharpener uses a ceramic disc system that takes care of the angle for you—just roll the knife back and forth, and that’s it! No complicated setups, no extra effort—just effortless sharpening. I have a high-end German knife set (Rheinstahl) that requires proper maintenance, and this tool makes it so simple to keep them razor-sharp without hassle. I absolutely love how convenient this is. Before, I had to rely on my daughter to sharpen my knives, but now, I can do it myself with ease. In fact, she was so impressed that she now wants one for herself! Looks like I’ll be buying her one for her birthday in August. If you’re looking for an easy, effective, and hassle-free way to keep your knives sharp, this is 100% worth it. Highly recommend!

Works as described. Super easy and takes all the guessing away. I was also surprised at how quickly it works. Wish I would have known about these 60 yrs. ago.( I am 77 now) Read more

Love this sharpner. It takes some work to get a new edge but well worth it. Read more

Got this for the hubby for Christmas and he loves it. He says it works very well. Read more

What can you expect for $29.99, not much. First time use, and I was blown away. You might have to fiddle around a bit for either small paring knives, or over large knives, but it did a fine job indeed. Been sharpening knives for the last 50 years(since I was about 10), and this does a simply amazing job for a quick top up. Is it the best, no. For the price I paid it’s fantastic, however. Read more

Works amazing Read more

It has sanding discs which after a couple of rolls it will consume and it won’t sharpen your knife. The knife is still dull as before after a lot of time wasted trying. Read more
