I took up ninjitsu sometime in college. It’s a Japanese martial arts that traces its roots back to the 16th century. The ninjas are stealth warriors. They are known back then as assassins for hire. As part of their training, they go for the quick kill. One of the popular weapons they used is the stainless throwing stars.

When you watch ninja movies today you see them throwing the stainless throwing stars at people and killing them instantly. That’s not the case. The stars were laced with poison and were meant to graze the opponent only. If thrown properly, you will graze the opponent and deliver the poison without your opponent seeing the star. Death will soon follow.
