The San Bushmen had many tools, but a lot of them were weapons. One weapon that they had was a bow and arrow. On the bow, the main shaft was about 40 cm long, and was made out of perennial grass. The arrowhead was made either of bone or stiff wire. But one thing that the Bushmen are famous for is what they put on the arrows. On the arrowhead, to make sure that their prey was dead, they put a poison. This poison is dangerous, and is made with caution. It is made of a poison grub, and in a small wooden cup. This poison is fairly lethal, and, if somehow, gets into your bloodstream, then you will most likely die.
