Make functional Shuriken throwing stars out of cheap tin disks from a hardware store.

Step 1: Materials

Picture of Materials

First off, I assume NO Responsibility for injuries you inflict on yourself or others in the making of/use of this item.

Materials You'll Need:

1.Grip-Right Fasteners tin disks ( I don't have the box to them anymore, but they're about 2-3" in diameter and you can get them at Home Depot ect for a few dollars a box(of 100ish))

Step 2: First Cut

Picture of First Cut

First, cut 4 slits into the disk at 90 degrees from each other. Make sure not to cut all the way to the center.

Step 3: Second Cut

Next, cut another 4 slits in between the first 4.

Step 4: Bending

Now, bend every other leaf on the star.

Step 5: Third Cut

Now cut points in the extending leaves.

Step 6: Flattening

Now, hammer the star flat to make it easier to throw

Step 7: Final Notes

Picture of Final Notes

Now you're done! Try googling for throwing techniques or something.

Since this metal is very thin, it is prone to bending when thrown at a hard surface.

If you have any sharp egdes like these, throw it away! If you're not careful the star will dig into your hand when you try to throw it.

zstarkovich (author)2014-04-13

Do these fly good and straight or are they too light? I throw the ones i made out of sheet metal from about 15 feet.

zstarkovich (author)2014-04-13

Jimmy Proton (author)KritoPerf2011-05-20

Why am I not surprised I found a comment from you on this?

Zhuriken (author)2011-03-03

Hey ;) I got a better and easier way to make a Shuriken wich is sharp and out of metal. Sounds hard eh? Well its damn easy. Go to some random store and buy a Pizza cutting knife (or whatever its called) and then break of the blade off it. Then you got a circle formed shuriken already sharp and able to penetrate doors if you throw hard. I tried it out myself and it works from a good range.

Very easy to make and a nice final result, you've done a good work. Unfortunately, those throwing stars are illegal in my country :-P

what country?

Spain. They're also illegal in much more countries, you can check it in google.

beatrice96 (author)2008-09-13

it's illegal if you kill someone with that shuriken. but least you can use it for pinning notes on you room to make more ninja-ish.

Iridium7 (author)beatrice962010-09-19

not in self-defense.

shadowfox009 (author)beatrice962008-10-13

robot117 (author)2009-08-02

hi i just googled Grip-Right Fasteners tin disks and nothing came up i also went to the home depot website and nothing came up how long ago did you buy these and where?

Jais1993 (author)2009-04-20

I thank you sir for this guide! I use steel instead of tin (makes 'em tougher). I sell them to my friends for $10. Great business!

Also planning to make a huge one.

sharlston (author)Jais19932009-07-31

where do yoy get the steel from???

You can buy sheets of steel at you local lowes, home depot, hardware store like Ace and Truevalue

originalwynne (author)2009-02-20

umm in not really sure if this would work but its worth a try, you could cut the bottom of of a tin of baked beans and use that.. i might try it if a cant find these disk thingies anywhere.

nave (author)2008-08-01

just cut up a soda can

casey321b (author)nave2008-09-20

too floppy and already bent. it also could not be sharp or wigh enough to stick in things like human flesh XD

nave (author)casey321b2008-09-20

hahaha yeah, it still hurts though...

casey321b (author)nave2008-11-29
