After seeing a few "Survival experts" on television cut themselves with a hatchet while splitting wood I felt compelled to post this here.
It's very simple and your not going to hurt yourself.
That's important especially if you are in a survival situation.
You just line up the hatchet on the wood like the picture and smack them both on a log or block of wood.
It's not being a wimp to do things safe. And besides that, this is easiest to do so why try to chop down from the end while holding the wood in your opposite hand.
