They look like the thorns of the honeylocust. While honeylocust is an ultra-common landscape tree, nearly all that get planted are var. inermis, meaning they are thornless. But the straight species has thorns identical to those you've shown us. Did the tree have pinnately compound leaves? Just about got to be a HL.

Thats got to be it, we have alot of Locust trees around and this tree looks just like them. Kind of reminded me of a Silk Floss tree.

Thanks for the info wisco.

Beautifully photographed.....but they are dangerous for feet, tires, horse hooves. Honeylocust, honeysuckle....chain saw for both.

I am amazed, at their sharpness, and strength.

def. a locust. was a real joy to mow as a kid. those thorns go right through your foot [after it goes thru your shoes]. thanks for the memories …. ^_^
