Katana Sword





Introduction: Katana Sword

The sword is pretty durable and pretty strong. You can swing it but it will hurt you wrist a little bit. It looks pretty much like a samurai sword maybe a little different but it works. Don't swing at anybody for it will hurt. I would say practice soft but no hardcore swinging. Oh yeah, this is my first instructable so feel free to criticize or anything like that, give feedback. The pix might not be clear considering they were taken with camera phone but you can still tell pix I think.

Step 1: Katana Handle

Use gray rods, and green connectors for the handle. White connectors up at the top for later the guard. The handle is pretty self explanatory but it could still be a bit tricky. The black little pieces on the handle, it may make holding it more comfortable but they make the sword a little more sturdier.

Step 2: The Guard of the Sword

The guard can be really tricky to put together. Hopefully my instructions will be enough. But if you look at the pix then I think it is pretty well put together. Connect little while rods onto the white round connectors. Put green connectors onto little white rods as shown.

Step 3: Starting the Blade

At the top of the handle where the white connectors are, the tips of nine gray rods are sticking out. hook orange connectors onto those tips, put blue spacers as shown.

Step 4: The Blade and Some Tips for It

The pix show a tip of how to make the blade and make it easier on you. On the blade, the gray part, takes three layers. Start with the middle gray piece and fallow the pix. Once you got the middle in, the rest you can do from there I think.

Step 5: Extension for Handle

If you want to make the handle a little longer to resembling a samurai sword, add on. Rebuild the handle but way shorter and connect it to regular handle w/ orange connectors. If you were able to follow the instructions I laid out, then you have yourself a descent knex katana.

    You should make a sheath, but great sword!!!

    nice sword but it uses lots of pieces! p.s very realistic!

    I'd have to say, this is a nice sword. I think it falls more under the category of ninjato than a katana. Great instructable though!

    I agree. I was surfing instructables looking for information on DIY metal forging when I stumbled on this. Kind of misleading.

    What do you mean...kind of misleading?

    I mean that you advertised it as a "Katana", not a "Katana made out of K'nex". If this were a site devoted only to K'nex that would be fine. I clicked on the link because I was looking up information about forging weapons out of real metal at home (yes, people do this, and it's surprisingly easy). Not to say it isn't a cool instructable, but you should just make the title more descriptive. Nice work! The best thing I ever built out of K'nex was a crappy block pistol.


    a EXTREMELY simple blade anyone who cant build from these pix post i can help

    Wait, if you were using like a real and hitting a tree or wall something, of course it's going to break. Remember the sword isn't steel.

    i thought it was a real sword... its that good lookin... and pics r kinda blurry
