Humans have manufactured and used bladed weapons from the Bronze Age onwards. The sword developed from the dagger when the construction of longer blades became possible, from the early 2nd millennium BC. Swords longer than 90 cm were rare and not practical during the Bronze Age as this length exceeds the tensile strength of bronze. It was not until the development of stronger alloys such as steel that the longsword became practical for combat.
Swords replaced with canes?
As the wearing of swords fell out of fashion, canes took their place in a gentleman's wardrobe. Some examples of canes, those known as sword canes or swordsticks incorporate a concealed blade. The French martial art La Canne developed to fight with canes and swordsticks and has now evolved into a sport.
