Introduction: Metal Ninja Star

This Instructable will show you how to make a very simple ninja star with something everyone probably has in their house and you can also make chili with it!!!!(dont throw this at anyone it can really hurt someone,i got my to peirce 3 inchs of drywall.)this pic isnt the real nija star you will be building srry.

Step 1: Gather Materials

To make the ninja star you will need:

-One large tomatoejuicecan(works the best)
-A can opener with the pointy thing as in the picture.

Step 2: Step 2

Step2:Make 2cuts with the pointy part of the bottle opener across from eachother like shown in the picture.I didnt have any tomatoejuice so I used a tuna can but the large tomatoe juice can works the best. You will have alot of trouble making it if you don't have a tomatoe juice can.

Step 3: Step3

Now do the same thing just turn the can and make 2 more cuts across from eachother as shown in the picture.

Step 4: Step 4

Now cut between all the other cuts evenly as shown in the picture.

Step 5: Step 5

For this step cut on the 8 flaps and then it should have sharp points on it,do this on the next 7 flaps and it should fall to the bottom of the can but if one of the points is still stuck to the can take pilers and twist it off...................then find a flat surface that is hard like your garage cement and then take a rubber malet or your feet and flaten the points so they are level and your done.Srry there are no pics for becuase my camera ranout of batteries. Try making 2 ninja stars and then hotgluing them together for a stronger impact or something like that.

    这是忍者飞镖上的8个字,是中国繁体字,你知道它是什么意思吗?

    hey idead could i add for fun a small static charger to the metal so in thery i would have a nija star knock down strike evry time

    I wouldn't suggest hammering it out on the cement... it chips too easily. I would suggest some sort of strong metal sheet, or an anvil.

    i had an old cassette tape eraser that had metal that held in the magnets and i made a real one. now i can say i made my shaken out of a cassette tape eraser.

    I'm sorry but your also wrong and right at the same time.

    I teach Shuriken Jutsu .
    firstly the word Shuriken is from very old Japanese and translates as "Sword in the Hand " .

    the modern confusion over the terms arises in the translation from the Japanese Kanji the word for the round spike is Bo-Shuriken (stick shuriken), the term for the round flat disk shuriken was Hira- Shuriken or Kurumaken (wheel/disk shuriken) or simply Shaken. 
    the terminology depended entirely on which Ryu  (school) the tool came from - each Ryu's blade style was usualy so distinctive that the Ryu could be identified by the blade shape.

    but, the majority of the older Ryu taught the  terms for the multi pointed throwing knife is a shaken, a shuriken is a spike that is thrown.

    a Shaken is a type of shueiken stupid

    You're calling him stupid? If your going to put someone down for "being stupid" at least spell correctly.

    Spelling mistakes don't increase stupidity, lack of knowlage (Specificially that you don't know said rule) Does.. Dumbass

    I do sincerely hope, to a level you do not even understand, that your misspelling of "knowledge" was intentional...

    Unless, of course, you were referring to the urban dictionary definition (which happens to be rather crude), of "knowlage", in which case I have NO CLUE'' as to how that could increase stupidity....

    Your icon is correct.

    I should actually try that. I never use that. So I am kind of used to fixing my own typos. If I have a typo it was probably done just to use slang.

    real shuriken are actually illegal at least in SA & wherever the mythbusters live
