Ow - that hurts! Did it once on a machine. Those rings can be mean sometimes.
Man That's a big "hedgerow" tree. You know, I never heard about Osage untill I got to reading all the selfbow threads a few years back (hailing from New Hampshire originally, and not getting into bows much until late in life). Now I love it and have a slug of Osage bows, and am working on another. Was Osage originally an imported tree here in the US, and if so, was it one of those trees they advertised in all the magaziness (when I was a "younger"), as a fast growing hedgerow,border/windbreak type planting? Just a thought I've often had and been curious about.
