You have to remember that Dan is talking about splitting three inch splits, not logs, I think using an 8lb. Splitting Maul would be unsafe.
that's why I take a break after 10- 15 minutes.
it doesn't all have to be done at once I can get better results with a chopper and minimal effort, A maul would be a good choice for an experienced individual splitting a lot of large logs 8" - 14" or so.
common sense and safety practices go a long way. tiring yourself out trying is not safe. True, but suggesting that maul to someone who is obviously inexperienced is not something I would do, regardless of taking breaks. If Dan decides that an 8 pound maul will safely split a 3" diameter log he may end up in the E.R.
to each his own... , I don't think the small hatchet he bought it the right tool for the job. No it is not.
So I have to disagree with your suggestion of the Splitting Maul... sorry.
I'm just looking out for the safety of a fellow member.
