Soo i went on a walk with my dog and had my mind set on hunting Burls, i searched the internet if locust had Burls, they sayd they had and the Wood would be one of the most dense Woods u could find. So i went to a small forest full of black locust and found a death tree withmultiple Burls on It. And hard is was... The Saw i had with me was sawing like im trying to cut bricks with It, and it is, or was a verry Sharp Saw. I Will cut one of the Burls into roughed overlay shape, seal It and Will boil It to speed up drying, the other ones i will seal and let normal dry for future overlays or handles for bows or knives. I also found a death tree with verry thick growth ring ,as far as i have seen yet 1 Will pick It up in a few hours.
