This is how to make a throwing star from a hard drive platter. With this design I have gotten penetration of about a half an inch in a piece of card board with practice.
Caution : These are not toys, you could severely injure yourself as well as others. i assume no responsibility for what you do with these.
Step 1: Gather Materials
Scissors (Don't Use Your Best Pair They Dull Quickly)
Hard Drive Platters (One Per Star You Plan To Make)
Step 2: Draw Lines
Layout the line by using the pictures.
1) draw line across the cd at about the half way point. to make a plus sign.
2) measure up any where from one eigth inch to one half inch from the middle of the circle along the lines drawn in step 1.
3) working line by line draw in the lines from the edge of the outer edge of the lines drawn in step one, to the marks made in step 2.
Step 3: Your Done
Then Cut Around The The Out side lines to get a star shape.
Then your Done, now go throw your star at some targets!
