So I'm self-learning a bo kata (shushi no kon from Matayoshi kobudo) and got to wondering what an actual traditional or authentic Okinawan bo is like? I see various makes and styles. Red oak, white, etc Some have the same diameter along the whole length while others taper towards the ends. I assume the tapered versions are more for demonstrations as you can whip them around a bit quicker but they wouldn't hit as hard in combat. But maybe that's wrong? The tapered ends would concentrate more force in thrusts? 6ft seems a common length but then other seem longer than that. Is there a consensus on what bo were like "back in the day" or is there no right answer?
