I have some
Most sawmills will have it.
By the way... while I love osage above others. I also like a yew core with osage on the belly, or just bamboo and yew... single core or tri-lam... what a lovely, lively combo. I also really like cherry, and have some walnut, sassafras, red cedar, locust, maple and others that I want to play with.... oh yeah, don't forget about bamboo... boo back, boo core, osage belly. Use your imagination.
