Not to worry, the bone is thick right there.
Murphys` law... anything that CAN go wrong...will.
Once several years back, I was "sharpening" an already scary sharp Zwickey, that was mounted on a wood shaft, and my new wife bumped into the shaft hanging out behind me, and drove the head into my leg. Almost ZERO pain, and almost ZERO clotting ability.
I promise to learn from your mistake, if you promise to learn from mine. Don`t assume the person walking behind you will not bump into your arrow.
