Curved Rolling Sharpener

I've never really been skilled enough to use a steel for anything more than light honing, and most domestic knife sharpeners are either ineffective or brutal...This is neither. This is subtle, controlled but powerful, and did a great job of restoring my favourite but sadly mistreated knife giving it a fresh sharp edge. It's surprisingly theraputic to use, and extremely straightforward since the blade is held still and at exactly the right angle by the magnet base, and the sharpening surface is held vertical by default. No more worries I'm making things worse.You can see this sort of tool at very high prices, but this seems to work fine and at £14.99 at time of review seems like good value to me.

I was sceptical that this rolling device would be effective in sharpening my knives but have to say I was proved wrong.Whilst the technique requires a bit of practising, the instructions are clear and easy to follow.The box includes a solid angle block with two angled ends. The 20 degree angle is recommended for use with Western made knives and the 15 degree angle for Japanese knives. There are pads attached to the bottom of the angle block that help to stop the block from moving around when in use.The second part is a solid rolling sharpener with two different coarse ends for sharpening. There is a plastic cover that fits over each end when the rolling sharpener is not in use to keep it clean and dust free.To sharpen a knife you place the knife on a solid surface with the blade facing upwards between the angle block, which is magnetic and the roller sharpener. You then gently roll the roller back and forth for 2-6 minutes and then turn the knife around and repeat.To make sure the edge of the blade is straight (honing) you then gently roll the 1000 grit side of the rolling sharpener back and forth 6-8 times and again turn the knife around and repeat this.I tested how effective the sharpener was by using an old knife that I knew was not cutting as well as it used to and cut a tomato with it before I had sharpened the knife and after. The blade sliced through the tomato much more smoothly and did not require any pressure.Overall this knife sharper requires very little storage space, is reasonably priced and works a treat.

Kimura Professional Rolling Knife Sharpener, Knife Sharpening with Diamond & Ceramic Plates, 15° & 20° Magnetic Angle Guides, Ideal for Honing and Sharpening of All Chef Knives, Japanese Gift BoxThe Kimura Professional Rolling Knife Sharpener is a high-performance sharpening kit that takes the guesswork out of maintaining razor-sharp kitchen knives. Packaged in a neat, branded cardboard box, it offers a simple, highly controlled method to restore dull blades without requiring traditional whetstone skills.Because rolling knife sharpeners use a unique two-piece system, it can take a moment to understand how they work together, but once set up, the process is effortless:Attach the Knife to the Magnetic Block: Place the angled wooden block flat on your counter. Select your angle by facing either the 15° side (for fine Japanese blades) or the 20° side (for standard Western chef knives).

Roll the hexagonal sharpener back and forth horizontally along the length of the knife from heel to tip. The roller maintains a perfectly consistent angle automatically as it glides along the counter.- Hone with the Fine Disc (#1000): Flip the hexagonal roller around to the fine #1000 ceramic disc end. Roll it back and forth along the blade for a few passes to remove burrs and polish the edge to a razor-sharp finish.- Repeat for the Other Side: Detach the knife, flip it around so the unsharpened side faces outward on the magnetic block, and repeat the grinding and honing passes.Key highlights of this sharpener kit:- Dual Magnetic Angles (15° & 20°): The magnetic base block securely holds blades upright at precise angles for both fine Asian cutlery and sturdy European knives.- Hexagonal Rolling Cylinder (#400 / #1000): Features a coarse #400 diamond disc for reshaping dull edges and a fine #1000 ceramic disc for honing and polishing.- Neat Branded Packaging: Comes presented in a clean, custom-branded cardboard box for easy, organised storage.For anyone looking for a foolproof way to achieve professional-grade sharpness without damaging valuable cutlery, the Kimura Rolling Sharpener is a brilliant piece of kit.

I bought this rolling knife sharpener to help maintain my kitchen knives and it has been a useful addition. The wooden base feels well made and the magnetic guides hold the knife in a steady position while sharpening. The design is simple to use and does not take much practice to get comfortable with.The diamond and ceramic wheels work well together. The diamond side helps bring back the edge on dull knives, while the ceramic side gives a smoother finish. The 15° and 20° angle options are helpful for different types of knives, although it can take a few attempts to get the best results depending on the blade.Overall, this is a good quality sharpener that is easy to store and looks well presented in the box. It keeps my knives in better condition and is much easier than using traditional sharpening tools. It performs well, although achieving a really sharp edge requires some care and patience.

I ordered this sharpener as our kitchen knives had all gone hopelessly blunt, and it is a lovely thing to unbox, the wooden roller and angle block have a proper quality feel, and it comes in a smart gift box with a Japanese look to it. The idea is simple once you see it, the knife holds flat against the magnetic block, which has a 15° side for Japanese knives and a 20° side for ordinary kitchen ones, and you roll the wheel along the edge.The magnets are strong, so the knife stays put and the angle stays consistent, which is where I always went wrong with a steel. There are 2 wheels in the roller, a diamond one that does the sharpening and a ceramic one that polishes the edge smooth, and the results genuinely surprised me, my old cook's knife is slicing tomatoes cleanly again after a few minutes of rolling. It is steady and safe feeling to use too, with no flailing about.Overall, I would say it is fairly priced for the quality, and it would make a lovely gift for anyone who enjoys cooking. A clever rolling sharpener that brings dull knives back to life.

I have a range of kitchen knives that I struggle to keep sharp. I have invested in a range of sharpeners over the years, including recently a whetstone. All have issues of various kinds. I was therefore keen to give this tool a go.It comes nicely presented and with clear instructions. The finish on the item is good, with Japanese symbols and covers for the two diamond sharpening stones. To test it I used the 20 degree end of the magnetic block, as per the instructions, since the knives were not Japanese knives. The knives hold well to the silicone pad on the angled block by means of the magnets in the block. I then rolled the sharpening stone along the blade and back using the 400 grit stone. I was surprised at the amount of filing that came off the blade (see photo). After turning the knife around and doing the other side, I used the 1000 grit end of the sharpening block to give a smoother finish. The rubber feet on the angled block help to hold it in place well while sharpening, but you do need to use one hand to hold it securely, with the other rolling the diamond sharpening block. Not much pressure is needed (nor can it easily be applied, since the blade will bend away), since the diamonds are very effective at their job. I would caution that it is best to do the activity on a tray or mat so that you catch the filings. I did not do this on my first attempt, with filings going on the table cloth.I was very impressed with the sharpness of the straight part of the blade, but I was not able to easily get the front (curved) part of the blade sharp. I have found this same issue with other sharpeners, so this is not a problem specific to this sharpener. By experimenting with various angles of blade and sharpener I was able to get somewhat of an edge on the curved part.I will need to use the sharpener more to get the best out of it, but so far I would say that the edge I have got on the straight part of the blades of a few knives (two carving knives and one paring knife) are impressive. As noted, the edge on the curved part of the blades is not as good, but better than before I sharpened them.This device is £9.99 (at time of review), which seems very reasonable given the effectiveness of it and appearance/talking point if given as a gift.

I have a set of older kitchen knives that had become frustratingly dull over time, and this rolling sharpener has been absolutely perfect for getting them back in working order. It is remarkably straightforward to use and feels like a massive step up from standard pull-through sharpeners.The magnetic wooden angle block is a genuinely brilliant piece of design. The strong N42 magnets grip the blade securely at either a 15-degree or 20-degree angle, depending on whether you are sharpening delicate Japanese blades or standard Western chef knives. This completely takes the guesswork out of the process and guarantees a consistent, precise edge every single time.The rolling mechanism itself is incredibly smooth and stable on the worktop. The dual-sided cylinder works flawlessly: you simply roll the coarse #400 diamond disc back and forth to grind away the dull layers, and then flip the roller around to the #1000 ceramic wheel to hone and polish the blade to a razor-sharp finish.At just £9.99, it feels incredibly well-made and even comes beautifully packaged in a sleek gift box. It is a highly effective, safe, and professional-feeling tool that has completely transformed my daily food prep. Five stars!

Despite some knife sharpeners of this rough design being poorly designed and made, this is not one of them. In use I found it near flawless for taking your time about getting a well honed and properly angled knife edge. Very clear step by step instructions are included in the box, and are well worth taking the time to study to get the best out of your rolling knife sharpener.As for things that usually trip up this style of knife sharpener, making them unusable and at times dangerous, this one passes with an almost flawless record. The quality of materials and finishing used is impeccable - and yes that is real wood, and well polished. The bearings run freely, with just a little friction as the kind used have rubber seals to keep damp and grime out of the bearing race, ensuring a long lifespan.The magnetic mounts for the grinding discs are detachable by unwinding them, though unlike many tightening them right down to get a hard lock on the thread does not bind the mechanism up preventing rolling of the sharpener as intended. The roller is also a satisfying to hold hexagonal shape (although some of the listing pictures at this time show a completely round one).When it comes to the sharpening process the blade is held in place by magnets behind the rubber on the angle block. This serves to keep the blade at the specified angle whilst you patiently work at the blade to hone it into shape. My only gripe here is that whilst those magnets are strong enough to encourage a gentle touch when grinding the blade, they should be significantly stronger for my tastes at least in being able to sharpen a little quicker when needed. This process is pretty easy when you get used to it, though in getting such excellent results a little patience is needed.The only other thing I would raise, is that whilst the included grinding plates are good quality and seem capable of lasting quite a while, I would like to see Kimura include a kit of replacement discs in the future - none are listed by them at this time, although other sellers have such things available which look to be a good pattern fit for these (look out for the ones with the same 'ear' notches).One of the good rolling knife sharpeners, well worth considering, and quite recommendable!
