I made a neat palm saver with an empty shotgun shell I found at a blind. I threaded two ends of the paracord through the empty primer hole, and tied them off so they couldn't pull back down. The I found a used shot cup, and hot glued it to the bottom, and cut the sides evenly. A quick passs with a torch made the sharp plastic edges nice and soft. The string is the perfect length to go around my hand or wrist while using it.
I was really tired of having marks on my hand every time I would shoot. Before this, I was just using a rag.
