m-p I agree it's nice to have your atlatl along. These darts hold up well with normal straight on impacts, but the joint is definitely a weak point on glancing blows. I've only broke two and both were from glancing off trees. I think a tougher take down dart would be all cane with a bone insert. Although I haven't tried it yet, I think if you were to cut a section out of your cane in between nodes and fit a bone or antler insert that extended 3 to 4 inches into each half so that the cut edges of the cane butted flush together and the insert contacted the nodes inside each half, the dart would be a lot stronger. In theory anyway. Just be sure to sinew wrap the cut ends and the nodes to prevent splitting. Once again, haven't tried it as of yet, just a theory.
