Aaron,
I have a piece of leaf spring that has a hole punched through it with a spike. in the last heat, I used a spike as a die and drove it into the bar to create a "spike underside" impression. Now, anytime I want to make anything from a spike that will need to stand up, I just drop a hop spike into the hole and drive it flat. The spike drops out and doesn't require grinding to stand up.
