That makes me think of some Blaxploitation movie made in the 70’s. Something like Shaft or Superfly. In such movies, it was common to see a Pimp or Drug Dealer holding a cane.
That cane had a long blade that would jut out of the bottom as the press of a button.

Or, someone else *might* have a Cobra head sword cane.

Maybe.
