It splits well when green or even half dry , dont know about full dry .
Mennonite farmers planted it around Black Creek BC for making farm things out of , it has self seeded in a few areas but is rare. It doesn't like our long cool springs so is the last deciduous tree to leaf out , prefers more heat and sun. A few bigger trees on perfect sites.
It makes one helluva splitting maul handle and axe handles , very strong . Dries very hard .
Saw one really beautiful longbow made of black locust , it shone golden .
