If you are looking for a more objective approach to what the "it" in this discussion is, you might start here
. While the Japanese sword has already been studied in depth from by Western metallurgy, this form of movement seems to be still something new to researchers. So while I would agree with you that more scientific knowledge of "it" would be useful, I think it is going to have to come from laboratory research in the form of peer-reviewed studies of the those who have "it", not from posts on discussion forums from people with no qualifications, either scientific or martial, speculating about what they think "it" is.
I don't how you would ever form a review panel when there is such a disagreement over what "it" is and who has "it" and therefore who can recognise "it".
