I agree... there are videos of every style that can be bought though one can find youtube videos that have "classes" as a result of covid lockdown.
oh and the book that was used in the karate kid:
"Mastering karate" by Mas Oyama...
there was one error with my post concerning savate:
there are 2 books written by Bruce on savate. The earlier one does have him showing the techniques and appears to be before savate was really organized. The techniques seem to be a bit more street oriented and he was wearing sweat clothes (workout clothes) and tennis shoes.
the later book had savateurs with tights and I think when they had colored rankings for skill level.
and they demonstrated the techniques.
My personal opinion is that the earlier book was better.
