I wouldn't carry anything bigger than a knife. Even the knife isn't practical, its just there for when someone REALLY should have been covering their six. Carrying a 4 foot sword will just get you laughed at. It's worth having because they cost $10, but don't bring a knife to a gun fight and expect to rack up the kills.
Not for glory, nor riches, nor honours, but for freedom alone, which no good man gives up except with his life.
