I would have prefered it if you would have asked for a favorite weapon in a good shooting game, as then I would say anything fast, small and inprecise (as I am not good at aiming in games).

This way I say my hands, but without anything in them. Maybe also a long stick. As the stick gives me some advantages but makes it still harder to kill with as any knife or shooting weapon.

As you see, I also am not a fan of guns or any weapon at all, the bad thing is that nearly everything can make a violent weopon in the hands of someone who actually wants to be violent with it.
