This is the first thing I ever made by banging on hot iron: a hook, from an old lag screw with a square head. I squared off the threads a little bit, then flattened the head into a plate, then made the bend.
I felt pretty confident about the hook, so I made a heart from a piece of rusty iron rod. I gave it to someone special.
The setup was very simple: just a portable coal forge with a hand-crank blower, a 3-lb Stanley hammer, and a section of railroad track for the anvil. A long-handled pair of slip-joint pliers served for tongs.
