Step 1: Rinse
Warm water and mild soap after each use. Never put your knife in the dishwasher; the harsh detergents and jostling will damage the edge and handle.
Step 2: Dry
Towel dry immediately. Don't leave it wet or in the sink; even stainless steel can develop spots if left damp.
Step 3: Store
Use a knife block, magnetic strip, or blade guard. Never toss it loose in a drawer; it dulls the edge and is a safety hazard.
That's it. No special maintenance, no fussy rituals. Your Shimeru knife is designed for daily use, and with these three steps it'll stay razor-sharp for years.
Every knife comes in its own presentation box, ready to give as a gift.
Unmatched Hardness, Surgical Precision
Discover the ultimate in sharpening performance with the Shimeru Diamond Rolling Sharpener, designed for chefs who demand durability, speed, and refined precision. Featuring ultra-hard diamond-coated grinding discs in #400 and #1000 grit, this system tackles even the hardest steels with ease.
Why Diamond?
Diamond abrasives are the hardest sharpening material available. The #400 grit disc is ideal for fast edge restorationβremoving chips, reshaping blades, and reviving dull edges. The finer #1000 grit disc polishes and refines the blade, creating a razor-sharp edge ready for precise slicing.
How to Use:
Start with the #400 grit to reshape or repair, then switch to the #1000 for fine honing. The rolling action ensures even contact, and the 15Β°/20Β° magnetic angle guide locks in perfect geometry for both Western and Japanese-style knives.
Perfect For:
High-carbon and stainless steel knives
Quick reshaping and precision finishing
Pros who want long-lasting sharpening power without water or oil
Crafted from professional-grade, heat-treated high-carbon steel, Shimeru Knives deliver exceptional sharpness, durability, and edge retention. From the first slice, youβll experience the precision that sets us apart.
Engineered for unmatched sharpness: razor-sharp blades that elevate your culinary experience.
Shimeru Knives feature uniquely designed handles that not only add a sophisticated touch to your kitchen but also provide a comfortable, secure grip for effortless chopping and slicing.
With a double-bevel edge sharpened to 15Β° (compared to the standard 20-25Β° of most Western knives), our blades allow for noticeably smoother, faster cuts.

Salegot this for my husband for his birthday and he loves it. he's always been picky about his knives and this sharpener is way easier than the stones he used to use. the magnet holds the blade at the right angle so you just roll it back and forth. after a few passes his old dull santoku was slicing through tomatoes like nothing. the 400 side fixed a small chip too. build is solid, no wobble. honestly impressed.
It's okay. Bought it because I saw the ads and thought it would be foolproof but there's still a learning curve. The magnet is strong but you can still mess up the angle if you're not careful. It does sharpen, my chef knife is better than before but not screaming sharp like the videos show. For $70 I expected more. The diamond discs seem durable but I'm not convinced it's worth the price over a regular whetstone if you know how to use one.
Solid sharpener. Brought my old German chef knife back to life with the 400 grit then polished up with the 1000. Wish the handle had a little more grip but it's a minor thing.
Got this sharpener for my husband since he's always complaining about dull knives. It works really well, the diamond discs cut fast. He sharpened our old chef knife and a paring knife in like ten minutes. My only complaint is the handle could be a bit more ergonomic for larger hands, but it's not a dealbreaker.
Ok so I'm not great at sharpening with a stone, always mess up the angle. This rolling sharpener is pretty foolproof. The magnetic part holds the blade at the right angle and the two grits handle everything from chip repair to polishing. Used it on a VG10 gyuto and it came out razor sharp. Slightly heavier than I expected, which is fine for use but a little annoying when I put it away in the drawer.
Ok so I was skeptical about these rolling sharpeners but this thing actually works. The magnetic angle guide makes it pretty foolproof, just roll it back and forth a few times on my chef knife and it's scary sharp again. The 400 side brought back an old beater that was basically useless and the 1000 grit gave it a nice polished edge. Feels solid too, not cheap plastic. Takes a little practice to get the pressure right but once you do it's way faster than dragging out my whetstones.
So I've been using whetstones for years but my hands aren't as steady as they used to be. This rolling sharpener is stupid easy. The magnet keeps everything lined up and you just roll it over the edge. Brought my workhorse gyuto back to shaving sharp in no time. The diamond grit cuts fast but the 1000 side leaves a really clean edge. Only took a minute to figure out the motion. Great little tool for the price.
Got this for my husband for his birthday and honestly I might use it more than he does now. The magnetic base holds the knife at the right angle so you just roll it back and forth and the diamond discs do all the work. I sharpened our old dull chef knife in like 5 minutes with the 400 side then finished with the 1000 and it slices through tomatoes like nothing. Feels solid in the hand, not cheap plastic. Came in a nice box too.
Ok so I was skeptical about these rolling sharpeners but this thing is legit. Used it on my 8 inch chef knife that was so dull it wouldn't cut a tomato without squishing it. Ran it through the #400 side maybe 10 times then the #1000 side and now it slices paper. The magnet holds the blade at the right angle so you don't have to think about it. Build feels solid, the diamond discs are aggressive but they don't gouge. Took me less than 5 minutes to get my daily driver scary sharp. Wish I bought this sooner instead of messing with whetstones.
This sharpener works great. I like that you just roll it back and forth and the angle is always consistent thanks to the magnet. The #400 side brought back an old paring knife that I thought was done for. Only thing is the handle is a little small for my hand, I have big hands so after sharpening a whole block worth of knives my fingers cramped up a bit. Would still recommend if you want a fast edge without learning whetstones. Maybe they could make a bigger grip version.
