I have a nice little Ozuku that has been my main finisher for the last 2 years or so. A few months ago I received a new stone that is a little bit harder and finishes a little better, so I haven't used the Ozuku until last night.
There is a slight crack in the stone, and at the end of the crack on the side of the stone a little chip had come out, but it was in the chamfer and had never bothered anything.
Before I put the stone up, towards the end of my finishing and the slurry was about gone and just water, I would notice I could just slightly feel the crack in it through the blade. It never affected my edges, but I could feel a bit of resistance in my stroke when I hit a certain spot.
Never felt it much with slurry, only when I was getting to straight water.
Last night didn't go very well at all. I got about three laps into finishing a razor I was working on and it really didn't feel right. I checked the edge and found out I had just bread-knifed the dang thing. Got to looking at the stone and saw it had separated a little and where the chip was had raised just enough to catch and ruin my edge.
So I lapped the crap out of it and completely got rid of the chip, re-chamfered the edges and snapped a couple wet pics. You can see from them it sucks the water right out of the stone where the chip was. I did a few more laps on it, but the feedback from the crack towards the middle of the stone is much more pronounced now, so I didn't want to continue on it.
Is there anything that can be done besides more lapping? I'm afraid if I keep lapping, I could just be chasing the same problem deeper into the stone. It's not a large enough crack to get anything in to stabilize it either.... I am at a loss on this one.
