The description says the dimensions so I knew this bar would be smaller than my whetstone. Other than that, this thing cuts better than another brand of leveling stone that I've also bought from Revain. Am I going to use this? Yes. But I can only use it on my walking stones. It evens them out with ease but doesn't flatten my thinner stones. I used the same "wet" process as the course stones on the smaller stones (1000, 6000) for about 15 minutes and my grid lines were still present on the stones and I had no "mud" in the grooves of it. leveling stone. Basically I recommend for the final leveling of stone, but not 1000 grit or higher.
