Introduction: Makeshift Kusari-Fundo/Manrikigusari

Picture of Makeshift Kusari-Fundo/Manrikigusari

In this instructable, I will be showing you how to make a very easy yet effective Kusari-Fundo or Manrikigusari. The Kusari-Fundo is a Japanese chain weapon used by Okinawans (the Okinawan variation of this weapon is called a Surujin) and ninjas.

This project was inspired by YouTube-er samurimaster500 and his YouTube video entitled "spike and chain wip" (I know its spelled wrong but that's the video's name. He's just not a good speller) in which he showed a makeshifht Kusari-Fundo that he made. So, credits for the original idea goes to him, I basically just posted instructions for something he made and tweaked it a bit.

Now, let's get this i'ble started!

Step 1: Materials

Picture of Materials
The materials that you're gonna need are:

  • Two wrenches roughly a bit longer than the length of your hand.
  • Chain, can be as long or as short as you like. I personally used one meter of chain, but that's just me.
  • Two locks.

That's it! Easy right? Now let's get building!

(I used pics from Google on this step cuz I'm lazy :-P)

Step 2: Chaining the Chain to the Lock and Locking the Lock to the Wrench

Use your lock keys to unlock the lock, insert the chain, insert the lock head to the wrench's hole, then lock it again. Pretty easy step, a self explanatory no-brainer.

Step 3: Repeat

Repeat the same thing with the other lock and wrench.

Step 4: Done!

And you are done! Now you have a homemade Kusari-Fundo that's high in quality but also very easy to make.

I looked at the product and what comes to mind is Holy shit!!!

p/s: just asking, isnt it supposed to be a scythe at the one end?

black hole (author)2011-10-10

Why not just use the padlocks and skip the wrenches? Seems like the locks alone would be enough.

magisterchief (author)2009-12-21

Future serial killer

Camisado (author)nate-dog2009-04-23

I'm a ninja enthusiast (not saying I'm a ninja), not a serial killer.

bowmaster (author)Camisado2009-04-25

I'm a ninja. I am not a serial killer.

Camisado (author)bowmaster2009-04-25

Yeah right, stop faking, kid.... The only person living today who can even be called a ninja is only Soke Masaaki Hatsumi of Bujinkan.....

bowmaster (author)Camisado2009-04-25

How do you now I'm not him? If can spell you know what happens when assume... Here is some prove that I'm Soke Masaaki Hatsumi: A video of me posting this comment!

Camisado (author)bowmaster2009-04-25

I know you're not him because Soke Hatsumi would never make an I'ble on how to play a ninja game with historically inaccurate content. He would consider that an insult towards ninjas :-P Tsk, tsk.....

bowmaster (author)Camisado2009-04-26

Did you watch the video? That is all the proof I need.

Camisado (author)bowmaster2009-04-26

Yeah, right, kid.... You're not rickrolling me....

bowmaster (author)Camisado2009-04-26

If you do want to accept the truth you don't have to. I know who I am and it doesn't bother me that you are to narrow mined to accept the improbable. Or even look at the evidence.

Camisado (author)bowmaster2009-04-27

Right, kid....

iSmack (author)Camisado2009-05-17

W00T!!! I got rick rolled by Soke Masaaki Hatsumi of Bujinkan!!! xD

Camisado (author)iSmack2009-05-18

My point exactly... It was a rickroll.

iSmack (author)Camisado2009-05-18

lol.... Yes, yes it was...

Camisado (author)iSmack2009-05-19


iSmack (author)Camisado2009-05-19

Yes I do see :D.... Do you have a genuine ninja outfit? Just wondering xD

bowmaster (author)iSmack2009-05-19

A "genuine ninja outfit" does not exist. The ninja use what ever works for them.

iSmack (author)bowmaster2009-05-19

o.O.... I still want a ninja outfit.....

iSmack (author)bowmaster2009-05-19

Mmmk. Thanks :D

geoslim13 (author)iSmack2009-11-03

there is supposed to be an ible on how to mae one soon

Camisado (author)iSmack2009-05-19

bowmaster is correct. Black ninja outfit does not exist historically. Nor do straight ninja swords (Ninjatos). Ninjas use what ever works for them, and as for the straight swords, Ninjatos are supposed to be Wakizashi-length blades on a Katana koshirae.

bowmaster (author)iSmack2009-05-18

I ninjad you in the face fool!!!

Camisado (author)bowmaster2009-05-19

Please stop trolling on my I'ble. Kthxbai.

nate-dog (author)Camisado2009-05-01

okay future ninja serial killer lol

Camisado (author)nate-dog2009-05-01

I'm not a ninja, I'm a ninja enthusiast, meaning I study the weapons and techniques of the ninja, but that's it.

wizard744 (author)2009-07-07

sounds like bowmaster needs to sign up for some rex-quan-do (napleon dynamite refernce) lol =-D

Camisado (author)wizard7442009-07-07

Lol, I don't really get it, but whatever =P

wizard744 (author)2009-07-05

i like it,ii made it for very cheap with stuff laying around the house you never fsil to make a great instructable good job

Camisado (author)wizard7442009-07-05

Hey, thank you very much for the great compliment!

goeon (author)2009-03-28

the pictures are not that great

Camisado (author)goeon2009-03-28

I know, I did this at night when I'm half asleep. I'll get better pictures for my next I'ble. But its pretty self explanatory, right? And the product is pretty cool, dont'cha think?

Udon (author)Camisado2009-06-24

Nah. I'm a serial killer ninja, and nothing says "I live in a trailer" more than using... spanners? to build this. Any particular reason why you used locks?

Camisado (author)Udon2009-06-24

Lol... Like I said this is makeshift, if you want better weapons check out my better I'bles, such as my Tonfa I'ble and my machete I'ble. I used locks because it would give more power to the swing, I guess. That and that's the only thing I have at the time.

Camisado (author)2009-04-01

Why the "hmmmm...."?

Berkin (author)2009-03-30

Awesome. Too bad I don't have any bullies around my place to use it on, though... XD

Camisado (author)Berkin2009-03-31

You don't necessarily have to use it on bullies..... Just for casual weapon practice :-)
