Just a strange question that popped up in my head yesterday during practice:
Aikido is based on sword movements.
This makes sense if one is a samurai: you only have to learn one set of movement principles.
But aikido was not intended for the samurai, so why base aikido on sword movements?
It leads (or can lead, or whatever ) to an effective martial art, that I don't wish to question. But doesn't it make aikido too difficult? One example would be that aikido often requires a distance in which you would be able to cut with a real sword, if you had one?
So my question eventually is: isn't basing aikido on sword movements in a way overkill? (As in effective, but more difficult than absolutely necessary.)
(I know what I have written above is not completely correct, but it is the closest I can get at this moment to that vague idea I had yesterday. Perhaps I'll do better after some replies.
