That and the least likely to get me picked up for public display.
Really? See I've never seen anyone with a quarterstaff in public. Never. And I have seen a few swords even, but a quarterstaff? Not even in San Francisco where people really think they are Peter Pan or Robin Hood.
Now, most martial arts that are not sports versions (judo and ti kwon do are sports, Sholin is not) teach weapons at the very high levels. They think it's best to learn the basic dicipline and master the basic techniques before moving into something that has much worse consequences. See, in order to be any good you have to have at least one person to practice with. And practicing with quarterstaffs is going to hurt. Big time.
That's why most people don't get very advanced in martial arts is they underestimate how much it really farkin hurts to learn that stuff.
