Swordstick
A swordstick or cane-sword is a cane incorporating a concealed blade. The term is typically used to describe European weapons from around the 18th century, but similar devices have been used throughout history, notably the Roman dolon, the Japanese shikomizue and the Indian gupti.
Popularity
The swordstick was a popular fashion accessory for the wealthy during the 18th and 19th centuries. During this period, it was becoming less socially acceptable to openly carry a sword, but there were still upper-class men routinely trained in swordsmanship who wished to go armed for self-defense. Swords concealed in ladies' walking sticks and parasols were also not unknown, as it was even less socially acceptable for a lady to carry a sword, or publicly admit that she knew how to use one.
Soon after their introduction, other "gadget canes" became popular. Instead of a blade, these would hold the tools of one's trade, compasses, and even flasks for keeping alcohol.
Construction
Malacca wood was the most commonly used material in making the cane shafts, and the standard grip was rounded and metallic. Today, designer and collector canes have sterling silver handles, and are made with wooden shafts made from various woods, including Malacca and bamboo. Ornate designs, such as animal heads, skulls, and various emblems may also be carved into the wooden handles; these may make them harder to wield, but some find them more attractive. Sword canes are most often made with stainless steel, rapier-pointed blades. While various mechanisms exist to lock the blade in place, accidents have been known to happen regularly with the simple push-to-release mechanism. Twist-lock mechanisms work well, as do double-locking mechanisms.
