A colloquialism associated with generating power is “it’s all in the hips”, but this is a little bit misleading, as the hips themselves aren’t really the source of the power.
That’s right, you heard me. Geometry forbids keeping your edge in line while the tip is below the hands.
I know it sounds ridiculous, but I have come across someone who thought they could bat a cut out of the way by hitting the backside of the blade with their hand…
Not too long ago I published the article “Accelerating the Wrist in a Cut – It Doesn’t Work!”. A few valid questions were raised, and they deserve answers.
Despite what you may want to believe, you CAN NOT have acceleration at the wrist and a locked structure at the moment of contact!
What does it matter how a tatami falls down? When the fall is all that’s left, it matters a great deal.
When cutting, the sword exerts force on the target, and the target exerts force right back on the sword. This force is what causes cuts to be less effective, and possibly fail. And where does it come from?
My first attempt at motion capture. It wasn’t great, but I got something. And you can all laugh and learn from my mistakes.
Hanging targets for test cutting doesn’t give any sort of realistic impression of what a sword would actually do. Take my word for it, or read to find out why.
If you have had (good) formal instruction on longsword cutting mechanics, you would have been informed that you don’t want to create a levering action between your two hands. Here’s why.
