Yes like said, black locust only has thorns on the limbs. Usuallly small like rose bushes. There is an occasional one on the trunk, but rare!
Black has thick ,deep, furrowed bark,light brown in color. Honey has slick thin dark gray bark! Also look for seed, fruit pods, size of bananas, near the base of the Honey locust!
Honey locust has been used for self bows, and is used by glass bowyers, like Howard Hill in Montana.
I would look for something else, personally, thats a large tree to handle.
