I do light construction with 2 inch and less green black locust poles.
I've built 2 "doors". They are a little wonky, but they work.
I've made a broom handle. Could have easily made many walking sticks.
I'm building a crossbow with them too. The wood is flexible yet stiff, perfect for a bow. Just need a trigger, arrow guide, and arrow and we can start target practice.
Planning on replacing the crappy wood of my kama with them when it gets bad.
They're easy to srip (some of them, some get frizzy when you strip them).
The bark makes excellent tying material, or crafts like basket weaving. Haven't used that yet.
