A few days ago I took this twisted, cracked and corroded copper rifling ring off an exploded artillery shell. After flattening it out on the anvil I was able to repair it and tidy up all it's edges. I then reshaped it and polished it. There's a bit missing due to activation of its original explosive task, but enough left to make an interesting bracelet. How would a conversation go that started with, "That's an interesting bracelet." ?
