I only split Douglas Fir and occasionally Western Hemlock and Cedar.Do you have any videos of splitting hardwood? Or stuff that doesn't split that easy? I don't think there is anything growing here that would split apart that easy, except maybe a chunk of windfall spruce with absolutely no knots. Usually needs more than one hit, or a deeper one that would make the handle hit the wood.
But youtube is full videos people splitting all kind of hardwood
