A caltrop (also known as caltrap, galtrop, cheval trap, galthrap, galtrap, calthrop, crow's foot) is an antipersonnel weapon made up of two or more sharp nails or spines arranged in such a manner that one of them always points upward from a stable base (for example, a tetrahedron). Caltrops served to slow down the advance of horses, war elephants, and human troops. They were said to be particularly effective against the soft feet of camels. In more modern times, caltrops are used against wheeled vehicles with pneumatic tires.
The Japanese version of the caltrop is called makibishi. Makibishi were sharp spiked objects that were used in feudal Japan to slow down pursuers and also were used in the defense of samurai fortifications. Iron makibishi were called tetsubishi while the makibishi made from the dried seed pod of the water chestnut formed a natural type of makibashi called tennenbishi. Both types of makibishi could penetrate the thin soles of the shoes such as the waraji sandals that were commonly worn in feudal Japan.
