I made this Z bar out of a peace of metal that had been removed from a circuit breaker. I've also tried to make tension tools from the metal frame from windshield wiper blades and of course the metal inserts from windshield wiper blades. Now I'm wondering what odd ball repurposed materials other people have used to make tension tools and picks from. Other than the more common windshield wiper blade inserts, hacksaw blades, piano wire, and under wires from bras since I've heard about all of those before.
