Last time I spoke with Paul he said he was coming up with a wrench/bottle opener. But out of titanium? Not bad.

The Budnitz Titanium Beer Wrench:
Our lovely Beer Wrench has a titanium 15mm spanner on one side, and a bottle opener on the other. Two titanium thumb-screws attach it securely the the water bottle mounts on most bicycles (including ours).
