Review: Unbelievable value, but not for low grit stones - I purchased this stone as competitors stones are outrageously overpriced IMO. I use this stone with Shapton Kuromakus in 320, 1000, 2000, 5000, 8000, and 12k grits. It works unbelievably well with all those stones except the 320 grit. It makes the 320 way too smooth and ruins the cutting ability. It works well as a Nagura stone as well with the 220 grit. It doesn't remove huge chunks of stone to ruin the lifespan of your stones, but quick enough to quickly restore a clogged surface. Putting a .001 straight level on it, id estimate it's well within that .002 spec. Amazing value for the money. Just grab one and don't spend double on something you don't need.
Review: Quickly flattened Japanese water stones - Worked very well at flattening my very worn Japanese water stones. I originally tried to flatten with 60 grit wet/dry sandpaper but it was taking a long time to remove material. This lapping plate quickly finished both sides of my stone in about 10 minutes. Wish I had purchased this sooner. Looks to be very well made. Very happy with the purchase.

- MirrorFlat Technology Ensures Even and Consistent Diamond Distribution Across the Plate
- 60% Larger Diamond Surface for Flattening Larger whetstones or Sharpening Wider Knives and Tools

## Questions & Answers

**Q: Are the diamonds electroplated or adhered to the surface of the steel?**
A: The monocrystalline diamonds are attached by electroplating after the plate is milled to within 0,002” (0,05 mm) flatness. Perfect for flattening whetstones

**Q: Can this be used on its own as a sharpening stone?**
A: Hi, yes, it can be a sharpening stone. But it's only 220 Grit (60 micron), it can only achieve a extra coarse effect. Thank you

### ⭐⭐⭐⭐⭐ Excellent quality product
*by D***N on October 17, 2023*

I bought the Sharpal Diamond lapping Plate over the DMT diamonds lapping plate because the following reasons: 1) the quality of the product is very impressive. Heavy iron plate ( chromed ) and rubber feet. 2) the diamond particles small sharp and the distribution across the plate is very uniform. See the picture ( zoom in ) from their add. 3) flattened my hardest ceramic stone in 3 minutes. Please see the attached photos . I thought the wet sand paper would have a hard time to remove it. However I have not tried yet . I will report later if I get a chance to do it. 4. The price of this is the best deal you can buy 2 of this diamond plates for one DMT plate. 5. You can send this product as Christmas or Birthday presents. All and all it is my best investment and I would buy the second one in a Heart beat. Kudos to you SHARPAL 👍
