Weapon o' Choice

OK, so lets say you have to defend yourself from a monster about your size with only one weapon. Any weapon you want. It's gotta be (semi) real. Like for example, I chose this Dirk. With a dog face. Stabbing my foes with the things I love. Please leave something in the comment section or something. I need to know so we can become a rag tag team and kill all the evil monsters. Or trap them in a ditch.
