Made some progress today.
Bought an angle grinder and some discs; now I just need a diamond tipped saw. I'm considering just buying a 115mm diamond tipped disc out of Bunnings, because it'll fit just fine in the angle grinder (need a special guard though). Makes shaping stones much easier, especially older/harder stones.
Stone is still harder than the discs so until I get a diamond tipped saw I can't make perfect SSS stones. Although it's certainly loving better than the little grout-remover multi tool I was using.
Went out the other day and found a few stones, I got two massive pieces, they were heavy as forget to carry all the way back to the house. Soaked and brushed them, got all the top soil off, and then I got to work on the first (smaller) one. Already got it down to a square shape, just need to flatten the sides now. It's a pretty neat looking sedimentary piece with some layering throughout it.
Pwn'd the forget out of my thumb earlier today.
Chisel slipped and slammed neatly onto the middle of my thumb. Left a decently deep cut. Serves me right for chiseling toward myself.
Also here's a picture of a little birdie sculpt I'm working on
