The splitting is one thing I wondered about if using it for something like flooring. Might have to use some clear filler type sealant or something. I imagine oiling the wood might help with the splitting but do not know for sure.
Yes it is hard. I have a pile of old line posts (30 years old maybe??) we took out when the cattle left the farm and once in a while if I need some quick heating wood will cut some up. You can actually see sparks coming off the chain saw chain and if it is an old chain about worn out where the cutters are not very deep it will break one off once in a while. Dried out the stuff is half as hard as steel seems like.
