The calthrop was originally smaller and made of cast bronze, I believe when India was trying to free itself from Britain... I could be wrong... In any case, they will land with a sharp point up no matter how they land. Scatter them across a roadway, and not only elephants, but any rubber-tired vehicle is done for. This calthrop is about 11" tall and is available for sale...
