Wondering if anyone has insight into this; I have 2 Sigma Power Ceramic 6K stones (1 with a wooden base & 1 without). I grabbed the 6k stone without a base a couple of days ago to do some honing and as I walked into the kitchen from the garage with it, the stone broke in-half in my hand, one half falling to the floor. The stone was dry and had not been bumped or dropped or suffered any known abuse (it is a second hand stone to me). Is this a common issue for this particularly stone? I certainly can see the value of the wooden base on my other 6k stone now. I am thinking of trying to epoxy the stone together, but maybe I need to provide a base for it as well.Regards.Randy
