This hero metal cane was used by Ben Affleck as Daredevil in the film of the same name.
In it’s folded state it appears as two billy-club style canes (as they appear in the holster) and when unfolded the two canes lock in place to form the double ‘extended’ cane weapon.
It has a small release switch to return it to the look of two single canes.

This style double-cane weapon is seen at various points throughout the film. This particular cane prop can be matched to Daredevils rooftop battle with Elektra and the bar-fight sequences thanks to the chips and damaged paint-work caused by Elektras sai weapons during the filming of that scene.
