The owl-shaped Winston 2.0 by Owl Tac has a likely use for self-defense that I don't intend to talk about here, other than mentioning that you should be careful about buying/owning one, depending on where you live. I just think it's a neat little trinket that would make a sweet addition to a keychain, or could be used as a paperweight at home. Either way, it's a fine bottle opening tool.

Shown in hand for scale.
