@yngmar more energy spent splitting it than is obtainable by burning it, that's for sure :)

@yngmar It’s worth trying. They usually don’t fall apart as fast as you’d expect. However, the splitters designed for a tractor's three-point hitch and powered by the PTO are usually the more heavy-duty ones.

@yngmar i tried birch bottom log to split with 'axe - hammer' bad choice, and yes, it went wrong - for an axe. So i borrowed some el-hydro splitter. It not split the log on first try - there a safety valve on hydro thing. So i made few tries on one side, on other side, there and there and log started to crack. Long story short - it worked without accidents.
