When you use the tile saw only cut into the bottom of the skeleton and not the flesh if possible. Once you cut a groove into the bottom where you want to separate it use a large flathead screwdriver, insert it into the cut and twist to break the remaining skeleton. The 2 pieces will still be attached by the flesh, just use a new razor blade to cut the flesh cleanly to separate. This is by far the best way to cut acans in my opinion. I hope everything works out for you. Waatch out once you cultivate one acan you wont be able to stop.
