A fist is more powerful than a impact weapon strike. What is going on?

You seem to be turning this into a "a knife beats a stick vs stick beats knife" against each other argument. Which means you aren't actually paying attention to what I was saying at all. I would explain again, but why bother? I am not going to waste time on your straw man. Based on the way this conversation, and past threads you have participated in have gone, I doubt you really want to discuss or listen to another in a real conversation, so I don't see why I should invest more time in it. Except to say you asked why would anyone bother to train in using a stick (esp. instead of carrying a knife) and I answered with multiple reasons why I think it has value.

Carry weapons all you like. Don't come complaining on MAP about any consequences for doing so. Don't expect a lot of support here for doing so.

Back to the original topic. The video is extremely flawed and doesn't prove anything. Multiple members have pointed out the various flaws. Which, apparently, should make you happy as you seem rather obsessed with carrying knives and batons around.
