I don't understand why peeps that are in this for the long haul wait until they have done irreversible damage to themselves before they move to a powered splitter. Get the dang thing BEFORE you wreck yourself.
If it splits well, I do it by hand. Just too much time to be saved versus using the splitter on wood that doesn't take much effort, or what feels like the same effort using the splitter,,,,,, at least for now, plus I enjoy it.
When things get nasty, I don't hesitate to fire up the splitter as I've decided I'm done with wedges and the 10lb sledge. Just no fun in that anymore.
