That's What Katanas Are For

Not my point. If someone pulls a knife in a fight, the chances are someone will get cut or killed.

Just wanted to chime in and say that this is true. A knife in untrained hands is more than useless; it's downright dangerous to its wielder. I'd take a good, solid club over a knife any day.

That's why, in the course of events, I'd really rather take a blunt weapon and try to break your elbow.

I don't know how it is in the UK, but using a lethal weapon for non-lethal attacks can get you in serious trouble here in the states. The courts can reason that, if you have the luxury of making nonlethal attacks, than a lethal weapon isn't called for in the first place, and BAM, you get an attempted murder charge, even if you were defending your life and wellbeing.

Granted, this sort of thing usually only happens with guns, but I think even a bat or the like would be considered a deadly weapon in this circumstance.
