Smashing two weapons together at full force...is just plain useless.
It might be Aikido, but it has not one thing to do with weapons and contrary to what you wrote...it has not one thing to do with dealing with a sharp weapon!
And again contrary to what you wrote...that mindset is more in line with kendo than weapons.
I love those vids of Otake showing a kata then explaining 'of course, with real weapons you would never do it like this ... for the sake of training, etc' (paraphrased). Some folks must have had the sound turned down and only saw the kata but never heard the explanation.
I'm more and more coming to the conclusion that for the sake of safety the baby has been chucked out with the bath water.
