Some years ago, I purchased a Fiero keychain from TFS. It was the anodized aluminum one. It was nice, light, and small. Unfortunately, it didn't wear well. The ring for the keys cruelly wore through the coating and into the aluminum, and the edges got all nicked and marked. Then the other keys and things in my pocket mostly wore off the engraving, until it was just a nicked, fairly rough piece of aluminum. I'd like to replace this with something that will hold up better. Any ideas?
