I have a bunch that is from larger shop doors - the 20' wide sort of doors, so the springs are 6" in diameter or so. I've made small prybars, handles for garden tools, plant hangers, and just had fun testing different twists. Though about making some 'wands' for the harry potter types.... I do find as soon as I've tapered it down or flattened it then it is tricky to work as it cools so darn fast and is tough stuff. One coil I had was square which was better. I've been wondering if I could use a bunch of the circle shapes in a gate, table or similar piece without much forging at all.
