Is the Klingon Bat'leth impractical?

OK, so you’re having a little disagreement with some stranger dude in the 7/11 parking lot and the argument is starting to heat up, and your girlfriend (or whoever) keeps saying “just forget it, let’s go” and you still feel like you have a point to make, and then this dude goes “hold on” and pulls an impractical Klingon Bat’leth out of his trunk. That when I would you say “OK, you win.”
