Canes are common pieces of equipment in many dungeons. They create intense, localised pain, are easy to use, and fit in very nicely with scenes revolving around punishment or discipline. The cane we see here has a handle to make gripping and controlling it easier
Canes are also common in naughty schoolgirl/schoolboy role-playing scenes
A cane is a flexible rod, approximately one meter long, which is typically made out of smooth rattan (see right) or fibreglass. It is round and typically between 5mm and 1cm in diameter. See example illustrated on the left.
It is used in caning, which is a form of impact play. It is also common in discipline or punishment scenes.
