We played chicken with knives. Two boys a few feet apart spread their feet. Each boy sticks a knife in the ground between his opponent’s feet.
Each boy brings one foot to the knife blade, so they are closer together. Then repeat the process.
Eventually, your feet are very close together. It gets more and more difficult to stick the knife between your opponent’s feet without hitting him.
If you chicken out, or stick the knife in your opponent’s shoe or body you lose your throwing knife.
We never played that where the teachers could observe us, though.
