As someone who has split a few logs in his time, that thing blows me away. It’s a perfect example of something that can be done easier/better if you had only taken a minute to think of it as a problem that needed to be solved. In other words, people use an ax and a stump because that’s just the way it’s always been done.
Of course, I’m leaving out the gas splitter because that is not a solution in a SHTF scenario.
I am working on a solar powered splitter! ;-)
