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.

orange dilemma says: Nov 27, 2008. 7:06 PM

I hate it when people call them ninja stars!! they are call ed shuriken oh and myserious ninja of fire-it isn't shaken but shuriken trust me my bro takes classes were he uses them and japanese swords and japanese bow and arrows and other asorted traditinal japanese weapons.

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

Flumpkins in reply to ThundertydusApr 27, 2009. 7:15 PM

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

Thundertydus in reply to FlumpkinsApr 28, 2009. 8:30 PM

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

Father Christmas in reply to ThundertydusJul 15, 2009. 7:55 PM

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....

Flumpkins in reply to ThundertydusApr 29, 2009. 1:42 PM

Your icon is correct.

Thundertydus in reply to FlumpkinsApr 29, 2009. 6:29 PM

Lol, Ty

Flumpkins in reply to ThundertydusApr 29, 2009. 6:39 PM

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.

Sir spicious says: Jan 18, 2010. 6:48 PM

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

neotom666 says: Dec 4, 2009. 8:06 PM

I LOVE MINJAS!!!!!!!!!!!!!(midget ninjas)

by the way... you have the internet. Before you call someone stupid for using terms that are correct (the hole shaken discussion), USE THE FREEKIN INTERNET for research.

Makes you look like a redneck that just found a aol 3.0 disk.....

heavy.metal.nguyen in reply to hellpilotJun 24, 2008. 2:09 PM

Were you trying to stick it to the side of your house or were you throwing it outside?

Landon Sullivan says: Mar 4, 2008. 5:32 PM

lemonie says: May 24, 2007. 5:32 PM

What is it with the Ninja stars and Shuriken? Please at least remove the metal from the chicken-can before publishing. A battery can be recharged / replaced... L

ninjaimasta in reply to lemonieFeb 28, 2008. 1:52 PM

tuna can

ArtemisBlue in reply to ninjaimastaMar 4, 2008. 7:30 PM

Nope, chicken. Chicken...BY THE SEA!

airsoft101 says: Feb 19, 2008. 3:08 PM

OK just made one don't think this is anything close to a real ninja star the foregone thing just bent when I pulled it out.

camondascia says: Feb 4, 2008. 7:11 AM

does anyone have a dremel??? I am a blade smith I make custom knives and swords and have been in the business for over five years i now make my throwing weapons via forge but when I was younger my four brothers and me used to take apart old bicycles and cut up the sprockets and make shaken (ninja stars) there is an almost unlimited potential in those little things and we got a lot of really cool designs out of these and if you have a decent target (one with the grain facing you not vertical or horizontal) you can even leave the gear whole and just sharpen the teeth. but this only works on the smaller ones the bigger ones generally have too much mass and don't stick well for the size of teeth but the bigger ones make better shaken anyway and they are already tempered so you don't have to worry about them bending due to a miss throw like you do with softer metals (tin and aluminum)
