About this item

  • 𝐖𝐡𝐲 𝐂𝐡𝐨𝐨𝐬𝐞 𝐃𝐢𝐚𝐦𝐨𝐧𝐝 𝐎𝐯𝐞𝐫 𝐖𝐡𝐞𝐭𝐬𝐭𝐨𝐧𝐞𝐬: Diamond sharpens even the hardest steels, including super steels like CPM-series, M390, and Elmax. Unlike traditional whetstones, diamond sharpening plates stay flat, require no lapping, work dry without mess, and deliver more efficient, consistent results.
  • 𝟑𝟐𝟓 𝐆𝐫𝐢𝐭 (𝟒𝟓 𝐦𝐢𝐜𝐫𝐨𝐧) / 𝟏𝟎𝟎𝟎 𝐆𝐫𝐢𝐭 (𝟏𝟓 𝐦𝐢𝐜𝐫𝐨𝐧) 𝐃𝐮𝐚𝐥-𝐒𝐢𝐝𝐞𝐝: Coarse 325 Grit (45 micron) restores dull edges; extra-fine 1000 Grit (15 micron) hones to a razor-sharp finish—offering efficient sharpening and honing in one stone.
  • 𝐋𝐚𝐫𝐠𝐞 𝐒𝐮𝐫𝐟𝐚𝐜𝐞 𝐟𝐨𝐫 𝐁𝐞𝐭𝐭𝐞𝐫 𝐑𝐞𝐬𝐮𝐥𝐭𝐬: The 8" x 3" (201 mm x 75 mm) size offers greater stability, better angle control, and supports larger tools—ensuring faster, more precise sharpening.
  • 𝐕𝐞𝐫𝐬𝐚𝐭𝐢𝐥𝐞 𝐅𝐨𝐫 𝐊𝐧𝐢𝐯𝐞𝐬 𝐚𝐧𝐝 𝐓𝐨𝐨𝐥𝐬: Suitable for a wide range of sharpening needs—not only various knives but also woodworking and edge tools such as chisels, plane blades, axes, and hatchets.
  • 𝐃𝐮𝐫𝐚𝐛𝐥𝐞 𝐌𝐨𝐧𝐨𝐜𝐫𝐲𝐬𝐭𝐚𝐥𝐥𝐢𝐧𝐞 𝐃𝐢𝐚𝐦𝐨𝐧𝐝: Exhibits superior structural integrity and fracture toughness, ensuring long-lasting performance and consistent sharpening under heavy sharpening pressure.
  • 𝐀𝐝𝐯𝐚𝐧𝐜𝐞𝐝 𝐄𝐥𝐞𝐜𝐭𝐫𝐨𝐩𝐥𝐚𝐭𝐢𝐧𝐠 𝐟𝐨𝐫 𝐋𝐨𝐧𝐠𝐞𝐯𝐢𝐭𝐲: The advanced Three-Times Electroplating Process firmly anchors diamond particles and precisely controls abrasive exposure—ensuring long-lasting, consistently sharp cutting surfaces.
  • 𝐌𝐢𝐫𝐫𝐨𝐫𝐅𝐥𝐚𝐭 𝐓𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲 𝐟𝐨𝐫 𝐀𝐜𝐜𝐮𝐫𝐚𝐜𝐲: MirrorFlat technology with precision-ground flatness (±0.002 inch / 0.05 mm) ensures even blade contact for accurate edge geometry and consistent sharpening results.
  • 𝐈𝐧𝐜𝐥𝐮𝐝𝐞𝐝 𝐀𝐧𝐠𝐥𝐞 𝐆𝐮𝐢𝐝𝐞 𝐚𝐧𝐝 𝐍𝐨𝐧-𝐒𝐥𝐢𝐩 𝐏𝐚𝐝: Comes with a 4-angle guide (14°, 17°, 20°, 25°) to maintain consistent edge geometry for optimal blade performance, and a non-slip pad to ensure safe, stable sharpening while protecting your work surface.
  • 𝟑 𝐘𝐞𝐚𝐫𝐬 𝐨𝐟 𝐂𝐨𝐦𝐦𝐢𝐭𝐦𝐞𝐧𝐭 𝐚𝐧𝐝 𝐒𝐮𝐩𝐞𝐫𝐢𝐨𝐫 𝐀𝐟𝐭𝐞𝐫-𝐒𝐚𝐥𝐞 𝐒𝐞𝐫𝐯𝐢𝐜𝐞: Headquartered in California, USA, with branches in Germany and Australia, SHARPAL provides easy and effective sharpening solutions. All products undergo rigorous testing to ensure top-tier performance and durability.

Amazing quality for the money

RanchpigNovember 14, 2025✓ Verified purchase

Originally saw this reviewed by YouTuber Outdoors55 who is a knife sharpening expert. He recommended based on years of experience. He wasn't wrong. This is probably the highest quality for the money diamond sharpener on amazon. It works as advertised and is large enough to handle bigger kitchen knives. Not thick enough to hold in your hand unless your doing small pocket knives, but easy enough to get a 2x4 cut to size and make a holder. Will definitely up your hand sharpening game. Fast and effective for shaping the steel, yet fine enough to put on a hair whittling edge. After 30 or so sharpenings, I can't see any deterioration and it's perfectly flat. Read more

Nice stone

J in MecostaJanuary 23, 2026✓ Verified purchase

This looks well made and works good. (I'm no expert on diamond stones). The course grits help to get an edge quickly and when used with a leather strop produces a very sharp edge. The guide was pretty useless to me but it could give a rough idea of the different angles to use. Mark the edge of a blade with a Sharpie and the correct angle becomes apparent and is probably more accurate. Watch Alex on Outdoors55 on Youtube to learn about sharpening techniques. Read more

Beautiful diamond board

Mitchell FamilyJanuary 31, 2026✓ Verified purchase

I recieved my diamond board today. It was packaged in a brand new crisp box with a lot of padding, sharpening degree guide, registration form providing an extra year warranty and some instruction materials. The diamond board is perfect. It's level, no blemishes, throughly covered, no rust I mean it is beautiful. I hate to use a blade instrument on it. I have ordered many diamond boards and this is the best I've ever seen. I'm serious I might not use it and keep it so pristine. It came on time between 4am-8am. The person that made this board must have been the guy who has been doing this for 40 years, never misses a day of work, cuts his lunch break short to make more diamond boards, loves what he is doing, loves his wife and kids, successful in everything he does, is modest and this is what makes him happy. I would love to hand him personally a tip and bow down to his superb craftsmanship. I would love to include a pic but I don't know how. If I figure it out I will attach it later. I will only buy from this manufacturer. Their quality is top drawer. Read more

Great choice for knives.

Kevin FlemmingOctober 26, 2025✓ Verified purchase

Along with a strop, this got my best D2 steel knives shaving sharp in minutes. The angle guide is great for learning the muscle memory needed for hand sharpening. Unlike woodworking tools, the bevel is so small it is almost impossible to register by feel. The guide let's me set and lock my position and recheck every few strokes. The two grit sizes are perfect for knives. Coarse gets to apex quickly and extra fine refines the edge fine enough for most work. Great addition to my kit. Read more

Good stone with an issue or two.

SCNovember 16, 2025✓ Verified purchase

It's flat. It cuts aggressively. But it's not quite what I'd hoped. I really wanted to use this as a flattening stone, but it loads fairly quickly and has to be cleaned. And there's the rub, you can't use water to clean it. So you brush and vacuum to get the residue out of it. I'll keep it just for the rare times I sharpen tools. I probably won't use it on my knives.

Great stone for a great price

Just MeDecember 30, 2025✓ Verified purchase

Great price for a very useful and consistently decent quality stone. I use it all the time. I also have the 325 and 1200 grit from Sharpal, but this 220/600 might be more useful for everyday sharpening of tools and knives that are getting hard use. I've been using one or the other of these over a year, every day, and I love that I don't need to use any liquid or otherwise prep it. Sometimes I wipe them off with a paper towel or scrubber, but mostly not. The 325/1200 came with a box with rubber feet that doubles as a holder and I just swap the stones onto that as needed.

Better than expected.

D. VaughnDecember 17, 2025✓ Verified purchase

Sharpal continues to prove they provide quality with value. I'm surprised at the low cost of this and expected the diamonds to start falling off. It has held up well and I've used it now to initiate first-stage sharpening on my camping knives. Even distribution and consistent grit of diamonds and the surface has continuity of grit after the significant usage. Plastic substrate is not a problem. WELL made and will certainly recommend this before the price increases. I was expecting to get a lower quality product but am pleasantly surprised. Am tempted to buy another one. Read more

Best deal on high performance diamond plates!

Stay Sharp PeopleAugust 4, 2025✓ Verified purchase

Sharpal product are excellent products with excellent quality and performance and a great price. Their customer service is world class so if you have an issue they will happily take care of you. Awesome value in this wonderful and high performance product, I'm a professional sharpener and have been for many years and when it comes to diamond plates sharpal are the best high performance diamond plates on the market at their price points, they are 95% as good as atoma except you get two grits for half the cost of a single atoma plate. These are incredibly consistent plates and last a long time I love them! For your dollar you can't find better diamond plates, not even close actually these are far and away the best deal on the sharpening market. Low cost, high quality and high performance with an excellent warranty and excellent customer service nothing else comes close! Read more
