  Works and works well... but only for certain knifes!

  I have bought a few different knife sharpeners and used them all, each one of a different type. There's really many ways to go for sharpening your knife. Each providing a step up in sharpness, but also a step up in complexity to use (both in skill and time it takes to sharpen).-Honing rod (not exactly a sharpener but does make it "sharper" in a way)-Sharpeners with a v ceramic in which you pull-Rolling sharpeners-Belt sharpeners-Rod based sharpeners-WhetstonesI think the nice middle ground for most people is either rolling sharpeners or belt sharpeners. I bought this really because sharpening with this is really simple, it takes barely any longer than the ceramic sharpeners and does a considerably better job.I think though, there are some big limitations...-For one, the magnet (that holds the knife) works great for wide knifes, such as chefs knifes... but is too tall to work for smaller knifes, such as utility knifes.>>Having a second smaller magnet as well would solve this.-There is only 1 single grit and a honing side. This works well for general maintenance, but if you have a heavily damaged knife it will take longer to sharpen and because there's no fine grit, you won't get that razor edge.>>Having a course and fine grit and a strop would be better... Or offering sharpeners with varying grits.These are the limitations of most rolling sharpeners out there... the next step up of using a belt sander, though can be found in compact sizes, it a little less "friendly" to use and wouldn't recommend it to everyone. Specially if you have a knife with a nice finish and worry about scuffing it.

  This is just completely incredible. With the Tumblr, there is no way you can miss a sharpening. This is so user friendly! I am amazed, simply amazed! In five minutes, I managed the create an incredibly sharp, scary sharp to be honest, on a chef knife! Before, I used sharpening stones but it was really mich more work. Now, with the Tumblr, I go from a pretty dull edge to a perfect one. When you use it, you know this will last long. The product is Top Quality! 110% satisfied! I cannot stop showing this wonder to everyone I know that come to visit!

  Works!

  Puts a great and fast edge on every knife I’ve tested. All pass paper test after. Maybe not for those who are suuuuper anal about getting the absolute sharpest edge, but perfect for someone wanting to restore their knives to near factory sharpness quick and simple.

  Good enough for tune ups

  It’s easy to use, but doesn’t work for larger clever style knives. Not sure if it is a learning curve, but this product doesn’t sharpen knives exceedingly well.

  Easy to use. Gets the job done.

  The instructions were easy to follow and the Tumbler got my dull knives sharp again in just a few minutes. I wish I would have discovered this earlier!

  Easy to use even for an knife sharpening novice!

  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
