Holy crap this stuff is tough as nails. I went to split one of the two logs I cut out, and I ended up giving up. The way I split them is I take a hatchet and hammer it into the end of the log, then I just keep hammering until I've forced the hatchet all the way through. It works pretty good with small to medium logs. I could barely get that hatchet into the end of the log even beating on it with a hammer. Hopefully once it dries a bit, it will become a bit friendlier.
