Hexagonal 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). Snap the flat side of your knife against the magnetic face so the cutting edge points straight up toward the ceiling.- Sharpen with the Coarse Disc (#400): Take the hexagonal roller and place the coarse #400 diamond disc end flat against the upright blade. 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. Giving it five stars reflects its top-tier build quality, consistent angle precision, and practical design.Precise angle control: Magnetic wedge block holds blades securely upright at 15° or 20° angles.Simple rolling action: Hexagonal roller with #400 diamond and #1000 ceramic discs grinds and polishes edges smoothly without complex technique.Complete sharpening kit: Includes both coarse grinding and fine honing discs alongside the dual-angle magnetic dock.Final rating: Five stars.

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!

I don’t see how I could give this any less than 5 stars. I have seen this type of knife sharpener before but usually closer to £40+. I have noticed cheaper versions lately though for about £20 and this Kimura Rolling Sharpener is half that! I wasn’t expecting much with such a bargain price but I was pleasantly surprised. The block and roller are both solid wood with embossed branding, nicely shaped, coloured and finished.The block has rubber, non slip feet, rubber protective ends with strong magnets underneath. The roller has a hexagonal shape which makes it easy to grip and roll. The ends rotate very easily and smoothly. The discs are removable (maybe replacements are available).If you haven’t used one of these before, I think it’s like a cleaner and easier version of whetstones. Like whetstones this takes more time than using one of the common drag-through sharpeners. Those scrape the and remove material quickly but with less finesse. This takes longer but gives a more refined edge. The little instruction leaflet included is very easy to understand.The block has 20° angle on one side (most common western knives) and 15° on the other (most Japanese knives). The knife attaches and is help in place by strong magnets. You then hold the block, place the roller alongside and run it smoothly and gently up and down the blade, starting with the 400 grit on both sides and finish with the 1000 grit.Overall, the set is very good and the quality seems much higher than the price tag suggests, so would make a great gift. The company offer a lifetime warranty. I'm not sure just how far that goes but they obviously believe in their product.

This is a really impressive piece of equipment. It looks stylish and well made, and the presentation box makes it feel like it would also make a lovely gift for someone who enjoys cooking.The sharpener itself is a simple but clever design, with a rolling sharpening wheel and two interchangeable discs: a #400 diamond disc for restoring the edge and a #1000 ceramic disc for refining and polishing it. The discs are magnetically attached, so they can be removed and replaced if needed.The two magnetic angle guides (15° and 20°) make it much easier to maintain a consistent angle while sharpening. The 15° setting is ideal for finer-edged knives, while the 20° setting suits many traditional Western-style kitchen knives.I normally use a sharpening steel, which is useful for maintaining an edge but can be a little awkward to use consistently, especially towards the tip of the blade. I found this rolling sharpener much easier and more satisfying to use. The magnetic guides helped keep the angle steady and I was able to sharpen the whole length of the cutting edge easily.After sharpening, my knives felt extremely sharp and cut beautifully. It's a simple tool, but it makes the process of sharpening knives feel much more accessible and gives very good results.At around £20 (the price I saw it at), I thought this represented good value for money. It feels like a quality product, looks much more premium than many basic sharpeners, and the replaceable discs should help it remain useful for a long time.Overall, I'm really pleased with this sharpener. It looks great, feels like a quality product and has made maintaining my kitchen knives much easier.

This is an excellent sharpener. So easy to use and for the first time I have really sharp knives in the kitchen. I used to use a steel but this piece of equipment gets the edge really razor sharp. Preparing veg and meat is now much quicker and more efficient. Speeds up my cooking and reduces wasted time.

I have enjoyed using this sharpener because it feels different from the usual pull through style. The rolling action is smooth and controlled, and the magnetic angle guides make it easy to keep the knife at the right angle without guessing. I like having both the diamond and ceramic plates because it means I can give a dull knife a proper sharpen and then finish it with a clean hone.It feels solid in the hand and stays steady on the counter while I work. I tried it on a few different knives and each one came out noticeably sharper, especially my chef knife which had started to feel a bit tired. The Japanese style box is a nice touch and makes it feel like a proper tool rather than a novelty.It has been a great way to keep my knives in good condition without sending them away or using anything complicated. I am really pleased with it.

Great little toll

If you want razor-sharp kitchen knives without the steep learning curve of traditional whetstones, this rolling knife sharpener from Kimura is an absolute game-changer. It makes getting a truly professional, razor-like edge on everything from heavy-duty chef knives to delicate paring blades unbelievably fast and easy.The magnetic angle guide is the real secret to its success. With ultra-strong magnets holding your blade at precise preset positions—ideal for both razor-thin Japanese steel and robust Western chef knives—you never have to guess or worry about uneven pressure. You simply snap the knife to the block, roll the sharpener back and forth along the edge, and let the dual discs do all the work.The combination of the coarse diamond disc for reshaping dull edges and the smooth ceramic plate for honing and polishing leaves the steel gliding effortlessly through tomatoes and thick meats alike. The heavy-duty wood and metal construction feels solid in the hand, and the rolling mechanism glides seamlessly across your countertop or cutting board.Plus, coming packaged in an elegant Japanese-style gift box, it unboxes like a luxury item—making it a fantastic present for passionate home cooks, professional chefs, or anyone who takes pride in their kitchen cutlery.It is an incredibly clever, beautifully crafted sharpening system that breathes new life into old, dull kitchen knives in just a couple of minutes.

This is very easy to use and the instructions are short and simple. I was able to get a very good edge on all my kitchen knives quickly as I do maintain them regularly. One extra thing you can do is to rub some tap water over the sharpening disc surface prior to use to get it damp. It does abrade much better when it’s damp. Good price too as I’ve seen them for over £40.

I have sharpened several kitchen knives with this system and was impressed by how easy it is to achieve a consistent edge. The magnetic angle guides hold the knife securely at either 15 or 20 degrees, making it much less intimidating than using a traditional sharpening stone. The rolling action feels smooth and the diamond and ceramic discs restored noticeably sharper edges after only a few passes. There is a slight learning curve if you've never used this style before, but once you get the hang of it, the results are excellent. It also comes nicely presented, making it a great gift.

This rolling knife sharpener is a great alternative to traditional sharpening stones, especially if you’re not confident sharpening freehand. The magnetic angle guides take away the guesswork by holding the knife at either 15° or 20°, making it much easier to achieve a consistent edge.The sharpener itself feels well made, with a premium finish, and the diamond plate removes material efficiently while the ceramic disc helps refine and hone the edge afterwards. I found the rolling action smooth and easy to control, and it didn’t take long to noticeably improve the sharpness of several kitchen knives.It comes presented in a smart gift box, making it suitable as a present for anyone who enjoys cooking or appreciates quality kitchen tools.The only thing to bear in mind is that, like any sharpening system, it takes a little patience to get the best results on very dull or damaged blades. Once you’ve got the technique, though, it’s straightforward to use and gives consistent results.Overall, it’s a high-quality knife sharpener that makes maintaining sharp kitchen knives much simpler, without the learning curve of traditional whetstones. I’d happily recommend it.
