The Original Tumbler Rolling Knife Sharpener™ – Easy Manual Sharpener for Kitchen, Outdoor & Utility Knives – 15° & 20° Angle Guides

I was constantly getting ads for this sharpener, so I decided to try it. I made the purchase awhile ago and I have to say that the sharpener was easy to use and did a great job sharpening. Unfortunately it quit rolling after a few months. It wasn't a gradual increase in resistance, it just stopped one day. Months went by while I sharpened my knives by hand until one day I got another ad on Facebook. I made a comment on the post about my issue and immediately Tumbler's customer service reached out to me. They also reached out to me on Amazon, where I made the purchase. They asked for a video of the issue and offered an immediate replacement. I am excited to get my sharpener back.The experience with Tumbler has been great and they really stand behind their product. The sharpener works great and it is a purchase that I am definitely glad that I made. 10/10 to Tumbler customer service and 10/10 for the product.

Great product. Does everything as advertised My dad taught me how to sharpen a knife but that’s time consuming. This is fast and easy . Holds it at right angle and roll it sharp . Great product. Made well also

It’s very easy to use and gets your knives sharp very fast. After the initial 10 or so minutes of sharpening when you first hone the blade, all it takes is 1 or 2 minutes each side thereafter to sharpen it again to retain your knives’ edge. Use it before chopping lots of food and you’ll have a good time cutting.However, I’ve had the Tumblr for a year now and the only complaint I have is the mechanism has gotten loud. It makes a very loud rubbery grinding noise and it’s distracting. Furthermore, the rolling wheels themselves seem to have gotten more friction. Not sure why this is but I cannot fix it. It’s also not possible to open the Tumblr and perform your own maintenance. Disappointed with the maintenance experience, but happy with the ease of use.My Tumblr still works and sharpens my knives well, but using it after a year now has more friction!

Easily the best sharpener I’ve owned. Easy to operate. You will have to make some adjustments for wider knives, but you’ll be able to make it work. Does a good job at sharpening knives and keeping good knives sharp. Well worth the purchase in my opinion.

As someone who spends a significant amount of time in the kitchen, I was intrigued by the concept of the Tumbler Rolling Knife Sharpener. This sharpening system promises an easy and efficient way to maintain the sharpness of kitchen knives, which is crucial for any cooking enthusiast or professional chef.Ease of Use:The Tumbler sharpener truly shines in its simplicity and user-friendliness. The setup process is straightforward, and the magnetic knife holder is a game-changer, ensuring that the blade is securely in place during sharpening. The rolling mechanism is smooth, making the sharpening process not only effective but also somewhat enjoyable. Even those new to knife sharpening can achieve sharp edges without much hassle.Sharpening Quality:The use of diamond-coated discs is a standout feature. The D35 grit size is ideal for removing the dull first layer of the knife’s edge, bringing back that much-needed sharpness. After using this sharpener, my knives easily sliced through tomatoes, meats, and even tougher vegetables like butternut squash, indicating a high-quality sharpening process.Edge Finishing:The addition of a stainless steel helix disc for burr removal is thoughtful and enhances the overall sharpness of the knives. This step ensures a finer edge, noticeable in the precision cutting it allows. This feature is particularly beneficial for those requiring high precision in their culinary tasks.Angle Options:Offering both 15 and 20-degree angle sharpening caters to a wide range of knives, from traditional to specialty blades. The strong magnets ensure consistent angles, which is essential for even sharpening across the entire blade. This feature contributes to the longevity of the knives, as uneven sharpening can lead to quicker dulling and potential damage.Design and Build:The Tumbler’s design is compact and robust. It doesn’t take up much space, making it suitable for small kitchens or limited storage areas. The build quality feels durable, suggesting that it will last a long time even with regular use.Overall Impression:The Tumbler Rolling Knife Sharpener is an excellent tool for both amateur cooks and professional chefs. Its ease of use, combined with the high-quality sharpening result, makes it a valuable addition to any kitchen. While it might be an investment compared to simpler sharpeners, the longevity it offers to your knives and the quality of sharpening make it a worthwhile purchase.

Bought this for my husband for Christmas. He loves it & uses it all the time. Great quality product! Sharpens all of our knives!

I am a skeptic and delayed ordering this until I was convinced that it worked and was dependable. This is the real deal. My knives are like razors and the process is easy. I wish I had not waited to get this. I am glad that I bought the original item and not a cheap knockoff. My research indicated that the knockoffs break and wear out.

Overall the Tumbler works really well across all of my Japanese knives. It is a bit clunky with the smaller blades on the steak and pairing knives but after a few tries I was able to easily get them razor sharp as well. Definitely recommend.
