Be aware that once metal is bent and bent back, it's permanently weak. No getting around it. You can use it until it breaks, but always be aware that if it's used hard, it WILL break. Make sure you position yourself to anticipate this so you don't get hurt.
I recently saw the PBS show on Japanese swords, and one of the commentators was talking about how bending metal changes its physical structure at the molecular level. He made his point by taking a coil of copper tubing and straightening it. He then tried to bend it back to a coil, and it would not move as easily. The bending changed the structure of the metal and made it more brittle.
