Step 1: Cutting Corners

So get you tin snips and cut a corner off that is big enough for you to comfortably through.

Step 2: Paint

Now if you want to paint it buy whatever color spray paint and make sure it's rated to paint metal. And make sure it's dry before you move on.

Step 3: Sharpening

Now all you have to do is sharpen it. First on the bench grinder,then on a knife sharpener to give it a finer edge. I tried it out on my bow target and it sticks in there nicely if done right. Enjoy it and remember to be careful.

    Ninja throwing stars are illegal in my state. Which is strange considering we don't have any license to own, or even carry guns here either. I think throwing knives are OK though? I certainly hope they are, because I've a couple throwing knives myself.
