Ian, ok with your interpretation of the Sasama, but I never wrote baldly ‘this is xxx’. I wrote. :’It seems to be a xxx’.
My conclusion is that some people can say the most offending things here, but for others it is forbidden to have a simple opinion.
When emotion takes it over from rationality, any serious discussion is over.
And about the koshimaki... well, a koshimaki is for a kabuto what a nakago is for a sword (dixit a most respected Japanese expert)
the more you know, the more,you know what you don’t know
with respect,
