I don't materially disagree. I'm just stating that there is still a place for those techniques and gave an example.
Maybe not to you but many of those techniques for preventing someone else from accessing your sword are similar, or sometime identical, to the Weapons Retention techniques used by armed police. So, while you may not have a particular use for a technique that prevents someone from snatching a weapon from your side, that doesn't mean that it doesn't have a place.
There's a huge discussion there. It's probably too big for this reply but I get it. I honestly think that a lot of it is because there are people who didn't understand the techniques but taught them anyway. My favorite example is the standard Karate-style "high block" and "middle block." I always believe that it was stupid and didn't "work" until I read Jack Dempsey's Championship Fighting and realized that all those Karateka had been told the wrong thing. It's not a "chamber your limb, then block" as two movements, it's a "swat block, then riposte with a backfist."
Well, yes and no. I mean, it's not as if the people way-back-when didn't have sticks and clubs to contend with. We just need to take it and find where it fits in our environment. It's not so much adaptation as just a recognition. Just like we don't see a whole ton of foot long, needle pointed, straight daggers attacking us in an icepick grip. Those old German deggen techniques still work just fine, we just might want to save those for later and study defense for attacks were are more likely to see today. I mean, does anyone think that a racecar driver doesn't know how to drive "on the street" because his competitive environment is "drive fast, turn left" or that turning left has no application when he's on surface streets?
We just need to apply the techniques and strategies which are appropriate for our circumstances at the time. Right?
Peace favor your sword,
