I can’t even wade through most of the misinformation in this thread.
First of all, don’t even bother reading the ARMA sites. Never did such a fount of misinformation about western martial arts exist before. The same is usually true for the SwordForum, though there are a handful of exceptions.
Second, the idea that western martial arts declined is historically inaccurate. It is still alive and well. Furthermore, it experienced perhaps its greatest renascence at the end of the 19th century, when tremendous advancements were made in both theory, practice, and pedagogy. There is even a spectacular dueling tradition in America that has endured into the twentieth century. The “decline” does not, as Bosda might have you believe, coincide with the rise of flintlock pistols. That’s bollocks.
In fact, we are in a midst of a serious renascence of western martial arts.
Japan certainly didn’t give up karate and kenjitsu. The development of aikido postdates the rise of firearms in Japan. Why should pistols have squelched martial arts development in the western world if not the east?
If you are interested in reliable information on the western martial arts, have a look at AEMMA, the AHF, IMAF, and finally, my own school, The Martinez Academy of Arms.
Let me see if I can clear up a couple of things.
Warriors in 15th century full battle harness were extremely fast. Anyone who does not believe this is welcome to watch trained armor fighting using traditional gear. Proper use of a two handed sword or even a jeu de la hache poleaxe is extremely swift. Mobility is also surprisingly easy in armor if it is made correctly, even for a little guy like myself, whose build is more useful for rapier and smallsword.
As for my opinion, as in all things fencing-related, it depends on the practicioner. The point of the katana, as I understand it, was sharp. A draw cut would not be effective, but a successful thrust to a joint very well might be. A correct thrust by a skilled samurai is hardly beyond the realm of possibility.
Finally, there was a famous duel between Maestro Julio Castello and a kenjitsu master in Havana in 1911. Maestro Castello roundly defeated one of Japan’s best katana swordsmen with a classical Italian dueling sabre in a public contest.
There is no superior style, as any serious student of martial arts should agree.
