I am a new poster to this forum, which I have found very helpful. I've done a bit of splitting with a wedge and a cheap axe. But now I have some very large red oak logs (see picture). The biggest are 24 inches across. I've tried with a twisting wedge and a sledgehammer, but can't get any purchase. The wedge just bounces out of the bigger logs I could try and rent a gas powered splitter, but would love to know if there's a way I can split them by hand. Any suggestions on the feasibility of this, and the appropriate tool? I looked at the Fiskars 28" splitting axe, which has been well received on this forum, but frankly it doesn't look up to the task. The store also had some heavier axes with a wedge-like head. Surely I need weight? And are they easier to split when green? Thanks for any suggestions.
