Review: very good value
Review: I’m a cutlery collector and sharpening nerd and I own all manner of Shapton splash and ceramic stones, old school Japanese full soak water stones, Arkansas black and translucent oil stones and high end and pricey JNAT (Japanese natural) stones for my cutlery and tools. I’ve been sharpening for 50+ years and I really like the Ultra Sharp stone family, but while the Atoma line is more expensive, it is the best of the pack. Why so many stones? It’s all dependent on what you want to sharpen - Japanese, German, stainless, regular steel etc. all require a different sharpening approach for ideal results. The Ultra Sharp all metal diamond coated stones excel at lapping (smoothing out the surface) of Japanese natural stones when they are new and can also be used to clean up natural stones and remove “dishing” from extended knife sharpening with JNATS. The Ultra Sharp are also excellent for chisels and planer blades that can easily gouge a even a hard natural stone. The great part about the Ultra Sharp stones is they are bullet proof, great for beginners as well as experienced knife sharpeners and cannot be easily damaged unless you do something really stupid. I have an Ultra Sharp 300/1200 combo stone and 3000 grit Ultra Sharp stone that I use weekly. That trio of stones will effectively service every tool blade and most common cutlery without additional stones for most users who sharpen a couple of knives a week or even a month. My one "con" with the Ultra 300/1200 combo stone is that when the stone is wet, it can be hard to tell one side from another (it's NOT marked) especially after a lot of use when the 300 wears down a bit. I stamped a "3" on the side of the metal stone so I could know with a quick glance which side was which. See my photos of the Ultra on the left in the stainless/rubber stone holder and the DMT on the right in the cheesy DMT plastic stone holder. The "edge shot" shows the steel Ultra Sharp steel core versus DMT plastic core. The DMT's work OK but I have them relegated to my wood shop for chisels, planes, common shop knives and my ubiquitous Swiss Army knife. Cutting wise, I prefer the Ultra Sharp over DMT because the Ultra has a solid diamond coating and the DMT uses a diamond lattice embedded in a plastic base. It’s just a smoother cut with the Ultra over the DMT but the Atoma stones mentioned earlier are the best of all three but cost a bit more. I know there is a lot of data here and I also hope that it helps!

## Questions & Answers

**Q: Are the diamonds embedded by electro plating or adhiesive ?**
A: The diamonds are electroplated onto the metal plates.

**Q: Does the stone holder in the picture come with the stone. If so can it be used with other ultra sharp diamond shaped stones**
A: Yes,  the stone holder in the picture does come with the stone and yes it can be used with all other Ultra Sharp Diamond stones.  In fact, the stone holder is adjustable and can be used with any stone that is between 6" and 9" long.

**Q: What is the flatness tolerance of these stones?**
A: +/- .001 (1/1000th) over the entire length/width of the stone.

**Q: What is the diamonds per square inch?**
A: The number of particles per square inch depends on the grit of the stone.   In practical terms, grit is the number of abrasive particles that can pass through a screen with specific sized openings.  A 100 grit abrasive particle will pass through a mesh screen that has 100 openings per inch.  (This definition is generally accepted but the values are approximate.  The thickness of the wire used to make a specific screen will vary the number of openings per square inch of that specific screen.)In general, a higher grit number represents a smaller particle size that will produce a finer edge.  A lower grit number indicates a larger coarser particle size that will remove material much faster.

I've used this stone for a year or two now, and it is holding up well. The diamond grit still cuts well, and no flaking or other flaws like I've read on reviews of some competitor stones. I didn't think I'd use the holder as it didn't seem to add much functionality, but I've found it to be a nice feature and always use it now with the stone. It's a nice addon touch to a very nice stone. Good quality and a decent price.
