I just purchased 500, 1000, and 4000 shapton glass stones. My old stones are soakers. When squirting water on the stones it just beads up and gets pushed off in a stroke or two. Is the purpose of the water just to wash off the gritty residue from sharpening? If it is for lubrication, are you suppose to splash it every other stroke? Stones act like they are severely dehydrated. Thanks D.
