Really Cheap Throwing Star

Possibly the easiest way to make a metal throwing star.

A can of anything (tuna works well)
A little opener (in the picture)
A can opener

Cut out one part, than go straight across and cut another.Do that over until it has eight parts out.(the top should look like this)

Open the can like you normally would and fold out the tabs.

Chuck it at your brother and eat the tuna!WARNING: May cause injuries, I am not responsible.
