I have not used Osage Orange, but have used Orange and Grapefruit, live in FL and both are very hard.
Most fruit woods are, especially after a good cure.
It depends on what the staff is going to be used for, usually they are finished with decking sealer only. I like the dull look, more natural and it works great for the long-term water-proofing of the wood.
Most of the woods I use are very hearty.
Sometimes I will poly them after the deck sealer, I they are to be display mostly.
I miss using a knife. I have advanced arthritis, tendinitis and osteoporosis, so this is my kit now.
