Lastly, (I'm not disputing with Nishi but just making a point). If Koreans who practice kendo/kumdo (I really don't like differentiating the two as they're really the same) think "Well, we've sort of borrowed the equipment but our philosophy and root are different because we had swords first." Does that make sense? What if the Brits who practice kendo all of a sudden say "well, we're using Japanese bogu, but we would like to put our own spin as we had knighthood and advanced armor, etc. Let's change the hakama to knickers (what Americans call the puffy pants with knee-high socks. don't know what they're actually called in the U.K.) and change the men-gane to a all-steel helmet with just a little slat to look out of", what does that become? Is that an acceptable way of practicing kendo? To put "your own" spin on it and changing tens if not hundreds of years of tradition and claim ownership? Just a thought.
