Hello, yes I am wondering what in the world is a "Caltrop". It appears to be a spiked ball made of either stainless steel or some kind of highly polished alloy. I have looked through all of my research papers and can find nothing on the subject of said Caltrop. Similarly I have went through all of my history texts and related materials but the enigmatic Caltrop remains a mystery. Is it a matter of national security? Are these things flying around at high speeds; so fast that they are nearly invisible? I am glad I found this site when I did, other wise otherwise I would not be able to spread the word that we all appear to be in grave danger from the demented artificially intelligent Caltrops.
