Office-Supply Ninja Stars

 by Xeracy
Make ninja stars to NOT throw around the office.

WARNING! This is a potentially dangerous project, both during the making process and what you do afterwards with it. Do not throw these at, near, around, within-sight-of pepole or animals. If you are under 18, or are uncapable of making sound decisions, do not follow these instructions.
If, for any reason, your harm yourself or someone else with this project, stop and think about what an idiot you are for actually making something that is so dangerous, then apply pressure with this project to your wrists and drag toward the inner elbow, because you are too stupid to live.

Step 1: Aquire Materials

Materials are as follows:
- Four (4) X-acto blades (standard size, nothing fancy)
- Double Sided tape (sticky on both sides)
- Regular Tape (Scotch Tape is good)
- Scissors

Step 2: Arrange the first two blades

Place two blades against each other at the base with the sharp bits facing away from each other.

Step 3: Apply double sided tape

Cut a piece of double sided tape and place it squarely over the bases of the two blades (like the blue square in the drawing shows)

Step 4: Place second two blades

Take the second two blades and place them on top of the tape, arranged perpendicular to the first two blades, bases together, with the sharp bits facing out.

Step 5: Cut some tape

Take a piece of regular tape thats about three times as long as the middle area of your star. Cut opposite corners off so it looks like the image. Make a second piece of tape look like a mirror image of the first.

Step 6: Tape it together

Place the first piece of tape on the star as show in the left image. Then wrap the sides around to the back and press the tape down firmly. Do the same thing on the back with the second piece of tape, but place it perpendicular to the first. This will hold your star together fairly well.

Step 7: Done! (and throwing tips)

There your have it! You're well on your way to becoming a master ninja of the office.

Good Targets: cork boards, bullitin boards empty walls
Bad Targets: people, animals

To throw, hold the tip of one of the blades between the thumb and index finger and then flick your wrist to throw (just like a frisbee). With some practice, you can hit a target from 5 to 15 feet away.

Remember Ninja's use violence as a means to an end. This type of tutorial should only be executed for extreme office measures. Watch the Office Ninja in action: http://www.youtube.com/watch?v=HZ5RPBguRkw

shammallamaman in reply to bic_manMay 4, 2008. 5:10 PM
They are sharp blades used on X-acto knifes.

This is extremely stupid. Shuriken are not toys.
shammallamaman in reply to Havoc2K7May 4, 2008. 5:06 PM
They are only dangerous if you are stupid.
Loveofchaos in reply to Havoc2K7Jul 7, 2007. 4:44 PM
shurikens can be very fun toys, you just have to not be utterly stupid and use good judgement and watch where yerr thowing
nchail in reply to LoveofchaosJul 11, 2007. 9:42 AM
exacly dont be a dumbass with these things it can get you seriously screwed.
Ben.land101 in reply to Havoc2K7Apr 9, 2007. 7:03 AM
yeah they are these are awsome!!
thingygoboom in reply to Ben.land101Apr 17, 2007. 7:55 PM
Nice. But these things could be really really painful. Shurikens are not toys, they are weapons though.
shammallamaman in reply to thingygoboomMay 4, 2008. 5:06 PM
Thy are only dangerous if you throw them at living things.
joedog86 says: Aug 23, 2006. 11:48 PM
C'mon people, ninja stars rock. Stop being so danged responsible and go impale something with a flying weapon of ninja-ness!
shammallamaman in reply to joedog86May 4, 2008. 5:05 PM
Heck Yeah!
gbosbiker in reply to joedog86Sep 4, 2007. 7:33 AM
hell yeahs
shammallamaman says: May 4, 2008. 5:04 PM
I love your instructable, i don't think anyone would be stupid enough to actually do any harm with it, and if they are they probably would do something else stupid anyway
kerpaul says: Oct 9, 2007. 7:21 PM
ok fleanine, i don't think you have to remind him that it's dangerous, because as you can see, he DID post that there are risks getting into this kind of thing. No one should be stupid enough to make these things in class or at the office. If they are that dumb, they shouldn't even be searching for weapons on instructables. With everything there come risks. you should know that. Even your paper shuriken idea....if someone is truly that idiotic, they can get a paper cut. oh noes. In fact, you can get killed walking into your kitchen. but you still do it. for god's sake, it's possible to drown in a puddle if your that mentally retarded. but ok, i'll admit that throwing sharp metal objects through the air is dangerous, but you cannot blame the person who posted this. instead, try telling the dumbass who threw it in the first place.
Aburame Shino says: Sep 8, 2007. 6:08 PM
I heart your Instructable. I look forward to making some in the future. -
fleanine says: Jun 21, 2006. 10:55 AM
OK, this does look like fun and all, but it is pretty damn dangerous. All I am saying is, if it was in an art class in school and some kid built one of these and it ended up stuck in your child,or someone you know, YOU would be pretty pissed. It isn't so much yourself you need to worry about, but the other guy...

TRY THIS INSTEAD, http://www.folds.net/tutorial/models/shu_2_piece/shu_2_piece_diagrams.htmland

Everyone has a piece of paper laying around.... and it is much safer for ANYONE, not just people comfortable with throwing CUTTING tools through the air...next thing you could do is take apart some scissors and use them like a throwing knife. Or better yet, attach the Xacto blades to opposite ends of a bic pen tube and whip that around the office.
Sorry, but this is just not a very "instructable" Instructable.
Before you know it, your employer will be sending you to anger managment or something.
gbosbiker in reply to fleanineSep 4, 2007. 7:45 AM
if people are stupid enough to make these in school or work and injure someone than yeah i would be pissed. The paper ones are for beginners. These and other "razor sharp" shurikens are for only experinced people not children or novices.
Ezpo says: Jun 28, 2006. 1:39 PM
Setting aside the fact that telling people how to make dangerous weapons is at best irresponsible, fact is disclaimers on a web site will not prevent lawsuits and prosecution. Strongly recommend Squid labs reconsider posting this kind of content
gbosbiker in reply to EzpoSep 4, 2007. 7:37 AM
skrew u man if a lawsuit did happen(which it will) the person that threw it is at fault not the person who showed them how to make it. And people can post what they want to post
chemy999 says: Jun 10, 2007. 8:28 AM
wouldn't it fall apart if you through it too hard?
TjT says: May 10, 2007. 9:36 PM
i dont want to kill myself if i accidently do something bad with this. even so i won't make it it's too dangerous. check out the alternatives by searching 'shuriken' on the home page search bar.
donesixfour says: Mar 24, 2007. 12:59 AM
i sound redundant sorry for my last comment it was filled with continuity problems and spelling and grammatic errors
donesixfour says: Mar 24, 2007. 12:58 AM
lol i agree with electrotyler to bring the human race a step ahead, we must first stop going backwards, i say that meaning that stupid people are the pregenators to destruction and would do well to eliminate themselves in an act of pure glee for themselves while the smarter "people" are free to acomplish what will bring us into a new era of knowledge instead of us having to supervise and reprimand the idiots who will inevidably drag us back for years to come. i mean thats all im sayin
Kirin696 says: Mar 20, 2007. 7:28 PM
My spelling is horrible i KNOW! pls forgive me.....
Kirin696 says: Mar 20, 2007. 7:23 PM
I have to agree take the stupid people out and you get smart people only. in a way think of medival times right? you had the dumba$$es who thought they could take on some knight....what happens next ou ask??? IAS DUMBA$$ GETS KILLED THATS HOW! Makes you wonder why the japanese in anchient times went "hey lets kill all of the stupid people if they get in our way!" "thos who agree say AYE!" AYE!
astrosapien says: Mar 8, 2007. 7:06 AM
X-Acto blades are blades for your average hobby knife.
sman17 says: Feb 26, 2007. 12:34 PM
cool, dangerous (which makes it cooler) but cool
electrotyler says: Aug 22, 2006. 11:35 PM
Considering modern life (generally,) we in the developed world have made it pretty easy for individuals to avoid untimely deaths as a result of shear stupidity. The use of seatbelts is enforced by law and today's plastic playgrounds are no more dangerous than loose cotton balls (if the cotton were in plastic bags, people could potentially suffocate. DANGER!!!) The way I see it, if stupid people are prevented from doing themselves in, they will be more likely to reproduce. Evolutionarily, the entire human race will become "dumber," due to the fact that it is so easy for stupid people to survive. These throwing stars are an excellent first step toward a smarter human population because they empower really dumb people and encourage them to do us all a favor.
IlluminatedAntichrist in reply to electrotylerFeb 10, 2007. 9:04 PM
Natural Selection Dumb people kill themselves while Smart people kill even more dumb people(either by giving them information which could get them to kill themselves or by straightforward kill.)However, the rate of human stupidity is spreading fiercely. We can only hope they die out before some moron launches an atomic bomb and destroys all of human life (both intelligent and stupid.)
Danny in reply to electrotylerDec 31, 2006. 10:39 AM
ya we need to eliminate the dumbness outa the gene pool since most dummys dont no wat a condom is they think that they are balloons that you win when u go toilet then this is the best solution
Loveofchaos in reply to DannyJul 11, 2007. 11:08 AM
well ive seen a few videos of people weeding themselves out of the genepool. well not themselves, but their means of reproduction with firecrackers and tasers... seriously how stupid are you to tase yourself in the balls?... and for fun? well we can sit back and laugh when they find out they cant have children.
Danny in reply to LoveofchaosJul 11, 2007. 4:23 PM
=D
backlash in reply to electrotylerNov 8, 2006. 11:46 PM
HOLY $#! you're my missing twin. ive said the same thing for years. plus since there are clear disclaimers he cant sue. and the human race will only improve with time. lets come up with more things like this.
shammallamaman in reply to backlashMay 4, 2008. 5:09 PM
I like your way of thinking.
stick1985 in reply to electrotylerOct 3, 2006. 2:25 AM
