Hey David, I just mailed your stave about an hour ago! I'm getting ready to email you when I saw the post. Yes, believe it or not...Hedge (Osage) has some thorns on it. Not like locust type thorns which are long and needle like, but hedge is more thick, short, and claw like and man when I saw claw like.....I ain't lying! If you get in the way of a trunk coming down and get whipped by one of those small limbs on it's way down......that's gonna leave a mark!
I've got scratches all over my arms and legs from cutting that stuff.
Good luck with the stave, and be sure to post some pics....better yet send me some too!
