Review: Hassle free in every way! - The first one I recieved had a tiny imperfection (a bump in the casting) but desertcart returns are so easy I got a replacement within a couple of days. The plate itself is great and cuts really nicely. I used to use nothing but water stones but having to flatten them all the time becomes a real pain. These dimaond stones are worth the investment and I'll be replacing my last two water stones once I have more funds.
Review: Unbelievable quality. - Great quality! So happy I finally took the plunge and bought one! Now I need to buy in fine/super fine. I already have the wave sharpener in fine and it really does a fantastic job on gouges, so won’t hesitate to buy more when I can afford to.

## Questions & Answers

**Q: What grits are these equivalent to? I am after 1000, 4000, 6000**
A: My understanding is XXC(extra extra coarse) 120.  XC 220,  C 335,  F 600,  XF 1200 and XXF 8000. I use up to the extra fine then move up to some fine water stones finishing on gold stone 8000 grit for mirror finish. Not got the diamond extra extra fine yet but if as good as the rest of the diamond stones will stop me having to keep flattening the water stones. Shame not a stone between extra fine and extra extra fine.  I have been happy hope this helps

**Q: Hi, how long will these diamond plates last?**
A: They did last as long as I expected, loosing about 50% of their abrasive properties after sharpening two planes and about 10 chisels

**Q: what is the grit count?**
A: I do not know directly but I think if you go to the DMT website the answer is there somewhere.  If not try a Google search with your question.

**Q: is the medium extra fine a one side or two sided plate and is it medium grit**
A: It's One-sided.  Also, it's 4000 grit, it's second from the highest grit stone they have, out of a range of about 6.  It's for taking VERY little material off.  It + 8000 Extra Extra fine are like the last two stones you finish on.
