Learn something new every day. We have persimmon trees here and there in some of our woods, but I've never known that it was supposed to be that strong or whatever. It doesn't generally get big enough to cut into lumber like we do with other trees. I may have to try some.
Osage orange is a very dense wood that is very strong in the lengthwise direction, but splits easily. I.E., it would make a great walking stick, cattle driving staff, bow, etc. But I'm not yet convinced it's the best choice for things that need holes drilled in it, or strength in more than one direction, or splitting resistance. It is VERY resistant to weathering and rot though. We have used it for fence posts for generations- there are still standing sections of our pasture fence that were set by my great great grandfather over 100 years ago.
Our shop is heated with a wood burning stove, and every year it seems like hackberry is about the toughest to split. (compared to oak, osage, hickory, ash, more oak, and various others) But I've never experimented with it otherwise, and it's not very pretty wood.
Thought I'd share something about locust wood. (I assume black, water, and honey locust. Not sure about the thornless varieties.) My grandpa once told me that this wood naturally gets very slick with use, and was highly sought after for making things such as the runners on sleds & sleighs, sliding doors, and stuff like that.
