I don't know a thing about different woods so I'm not sure if anyone would even be interested in this but....
A coworker of mine had a white oak burl die on his property and he's looking to sell it. Like I said I don't know anything about woods so I don't know if this would make good handle material or what but I told him I'd ask around just in case. I'm in SE Missouri or I suppose we could ship it if you want
He knows its usually sold by the pound but doesn't know the going rate so I'm sure he'd be open to negotiation. Hit me up if you're interested!
