Query: fast flat and easy

Hello,I have used this combined bench stone very much the last month on chisels, knives and bench plane irons and it performed really well on all.The stand is functional and it's easy to flip the stone from one side to the other.8 inch is a generous size... as far as you don't use it for huge axes.I already knew that the diamond surfaces feel like they perform better at the very beginning but it's just an impression. The harsh sound isn't there any more, it works silently now, but it definitely works!I think the speed and the "ever lasting" flatness are the big advantages of diamond stones and the DMT appears to be one of the best ones of that kind.It's nice, too, not to have to mess around with water or oil. I just put a small amount of water on it. That's enough. But you could easily work with the dry stone.Fine and Extrafine is good for sharpening but you need a finer stone for honing and a course one for the initial setup of bench plane irons.Bye, Herb.
