One of the oddest things I've begun to notice lately is that my increasing experience with swordsmanship (even though it's still not much) is starting to let me understand some of the subtler details in not only the system I'm most familiar with (i.e. the medieval German Liechtenauer tradition), but also other systems as well. A case in point is the Japanese koryu waza videos I watched last week; when I watched them the first time around after downloading them some three or four years ago, I had absolutely no idea what was happening. Last week, while I couldn't say I completely understood the techniques and the system behind them, a big lightbulb went up in my head about one feature that I simply couldn't wrap my head around back then: kiri-otoshi. My understanding of the geometry involved is still quite hazy but that's immeasurably better than several years ago, when I had absolutely no idea of how such a technique could work at all.
Enough rambling. Maybe I should go and pick the brains of some friends who are much, much more familiar with Japanese swordsmanship than me.
