Need help finding a movie, maybe 2.
I'm looking for an old school (70s-90s maybe) martial arts movie.
The only thing I can remember is that there is a fight scene on some scaffolding at an airport or something, in front of a building, and that one of the fighters has a boot knife, the kind that flicks out of the toe.
POSSIBLY the same movie, there is a movie that has a ninja with a poison dart ring, the kind where you remove the gem stone and beneath it is a poison needle.
It was 2+ decades ago when I watched the movie(s), and apologize for the lack of details.
