Breaking a Door Handle

I've been trying to figure out how we are going to accomplish one of our shots. The scene starts off with a close-up of a door handle being dropped on a table and breaking. In order to do this we need to wear down the handle until a simple fall will break it or break it then loosely glue it back together so it will fall apart again and still look convincing. Does anyone have any ideas on how to do this. Gluing the handle back together might look strange on camera so if anybody can think of a way to pull this off, please let me know.
