Of course. After all, doubling the speed will quadruple the kinetic energy Bingo. Good ol' F=MA where Mass and Acceleration are inversely related. Sometimes overlooked in sword conversations and a core reason I prefer speedier swords over the ol' battleaxe variety.
One of my favorite bits of sword trivia is taking an agile sword (usually a jian, but the KA side sword works too) and listening to the insanely sharp pitched tachi-kaze. When you hear the clean sound as it cuts through the air, you can perceptibly feel just how effective the cut will be.
How's the DT Gothic whistle, by the way?

Of course. After all, doubling the speed will quadruple the kinetic energy A reduction in weight doesn't necessarily correspond to an increase in velocity, though. And even when it does it only goes so far, because the sword is still propelled by the same old human body and there's a fairly low, hard limit to how fast your limbs can move. But yeah, 2 pounds is a pretty common weight for infantry sabers, for example. There's no reason to think a sword wouldn't cut just because it's not heavier than that. |

Can have lots of fun cutting with lightweight weapons. I have a cute little parang I sometimes put in the hands of first-timers for cutting because it's small, light (under 300g, iirc), and easy to control. They usually successfully cut with it. Bowie knives can be fun to cut with. Kukris, too. Tantos, etc.

This thread caught my interest and explains why a sword stick that I have cuts the way it does. It is a now discontinued Hanwei sword stick. I can’t remember the model but like most sword sticks the vendor was relating to Zatoichi who I knew nothing of or could care less at the time. I ordered two, this one and the Hanwei Blind Fury. As it turned out later I saw a 4 part video on YouTube of the making of the Zatoichi 2003? movie. This is a copy of that very sword. Actually they used 7, but... I’ve carried both but am drifting. That sword is considerably smaller than the Blind Fury and reminds me more of a wakizashi with its 23” blade and 570 g but for a long time I thought of it as a sword and tried to use it as such with two hands and always with disappointing results, while I could cut reasonably well using one hand. I just realized it was the speed difference. I don’t know why it took so long for me to figure that one out.

That's a good point about lightweight swords: they can be faster in one hand than in two. Light enough so you don't need the extra muscle to move it quickly, and one-handed gives good rotation acceleration just before impact.

It was the one-handed rotation that I was finally crediting the results to prior to this thread. Not to say it's one or the other, but both. Whatever, Zatoichi used both hands and has me beat by a mile. Hehe Anyone care to be my special effects man? There's an opening. |
