Yes, it's really an incredible object !
I have really thought about it many, many times :) I love it as much as I imagine the owner must have been devastated by its loss. In my opinion he must also be more resilient to these things than a Westerner who, I agree with you, deserves a good life-saving crisis !
Yes, all this craft knowledge that we have lost, but I am sure that if necessary, we will be able to rediscover it... Always an optimist ^^
Have a nice day, I hope you're well !
