No experience with cutting sharpening stones other than the old oil stone my grand father had which I dropped and broke for him as a child:-(
That said, my wet saw cuts granite, brick, ceramic, marble and concrete, fairly sure it will cut any stoneish material. Just like a any saw, you will loose all the material within the kerf of the blade so a smaller saw (7″ vs 12″) may have a thinner blade. If you don’t own one, you can rent one or maybe call around to tile stores and see if they may have one on site and be willing to cut them for a fee.
The other option is a tile blade on an angle grinder and cut them dry, would be much more difficult to hold the stone and cut it straight but might work if you are careful and take your time. (not as safe as a wet saw, use common sense and your knowledge of your own abilities)
Good luck!
