“not an easy weapon to use effectively.”
Quite true and most sword canes are “novelty items” with a sword only slightly more useful and of similar qualitry to a barbecue skewer.
But since we Americans have become such sheep about defending ourselves, the mere presence of something people think i=s a deadly weapon is enough to accomplish one’s goal.
Not long after 9/11 a plane was grounded, evacuated and searched because a picture of Osama Bin Laden was found on board.
TSA also regularly confiscates toy knives and guns that wouldn’t fool anyone outside of TSA,one time seizing a bracelet charm in the shape of a tiny revolver, suitable for threatening mice perhaps but so obviously not a real gun one is left stunned at the mindset of a TSA “officer”.
(Please, never call them agents, that is a special category in law enforcement with arrest powers. TSA likes to make people think their “officers” have such powers, they do not, in any form.).
