You're going to like that 8"x3" Belgian Blue. I have one and use it a lot.

I recently started using it for a purpose other than honing: I've been finish lapping my stones on the Belgian Blue. Nice!!! The stiction is a huge factor, but I like the smooth results that it gives to the surfaces of my other natural stones (I have not tried it on my Shaptons) that I'm probably going to lap the bottom side of my Belgian Blue and score some diamond pattern into the surface which should reduce the stiction and make for a great 4000 +/- grit lapping stone.

I bought some carbide tile hacksaw blades (inexpensive) that rather than having teeth, it's like a thick wire with abrasive bonded to it. It should cut the bottom of my belgian blue easily. I'll just score the surface down to maybe 1/8".

I'll post pics and results when done.
