No Wakeshine. Take the whole dahlia plant and saw it in half. Take off, use sharp knife, those tubers sliced by the saw. Those that "fall off" discard. If you cut in half you will have more than one stem...that's fine.
Please don't untangle every tuber. Not necessary.
as I said before, you are over thinking it all W.
When you see your bisected dahlia growing away next spring you will,have the confidence to separate or divide dahlias easily
