Review: Used it to rough hone my new chisel backs worked great.
Review: 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.

## 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
