Geometer's Cane

This remarkably rare walking stick doubles as a practical tool for the professional geometer. A tug on the handle of this rare cane reveals a tripod hidden within the shaft, on which the bullet-shaped ferrule is placed for sighting.

A similar cane is pictured on page 264 of Cane Curiosa: From Gun to Gadget, 1983, by Catherine Dike.
