Do you live near a working historic site (like Colonial Williamsburg, Greenfield Village Olde Sturbridge Village, etc)? If so they might have a working potter or a working tinsmith. The tinsmith should be able to make you a "use it up handle" out of tin for your Stein. Won't look quite the same but it looks sort of neat and you still have your Stein. I used to work at Greenfield Village (in the Sawmills, Machine Shop, and Carriage Repair and Wheelwright Shop) and have several mugs/steins with Use em up handles.
Maybe it's a sign that you should start using your 11th anniversary stein.
