Picture of How to make a duct tape sword
This is the second instructable in a series about how to make weapons and other equipment for LARP.
My main focus is that the weapons have to be safe, so kids can play with them without direct adult supervision, without getting hurt. And secondly so easy to make, that big kids, with help, can make it them self.

These weapons is perfect for a backyard battles or a game of LARP (Live action role play) in the nearby forests.
If you keep the design simple it is easy to make, and with adult supervision kids can make their own.

I tried to make the Skyrim steel sword, and this was my end result.
Whist making it, I used a Yoga mat instead. Because of the thinness of the yoga mat, I had to double the middle layer. I also found hot glue and scissors to be more effective.
Bamboo core, PVC piping handle (wrapped in hockey tape), and shiny silver duck tape I found at Walmart!

Hi Dovakin

You sword looks good. Glad to inspire you.

I wanted to make this for me and my friends, could you use 1/2 in.cpvc pipe to replace the bamboo rod? or will the pipe make it more dangerous?

PVC piping is alot more flexible! It shouldn't affect the force. PVC piping is a great choice!

If your worried about hurting people, add more foam. Or if you have lying around, a yoga mat to do a thinner layer.

I've used pool noodles for the padding and 1/2" SCH 40 pvc for the core. Noodles have a tendency to deteriorate over time more than the camping pads, but are a little cheaper. for the longer weapons (Pole arms, axes, spears, etc.) I go with 3/4" SCH 40 PVC to reduce whippy-ness, but add extra padding for the weight. I like the beveled edges you can make with layers of camp padding though.

cooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooool and how do you make it

U could make a ninja kantana out of this. All ur 'ables are Viking related. Nice.

OMG when I saw the thumbnail of that last pic, of them up against your couch, I thought the items were resting against someone's FINGERS - and I went WTF???  Miniatures?? How the hell do you make those out of foam and duct tape?
Haha, I had the same thought too.

OMG! This is so cool. See if I can get hubby to make something like this for our little guy. Thanks for the instructions.
We did it! Made two of them. My boys had a wonderful time playing sword fight and no one was hurt! :-) Thanks again for the tutorials. Excellent!

These absolutely rock! My son and his friends have been saving up for Nerf brand toys and now they can save some money and outfit their entire class. Reminds me of my dad making rubber band guns for himself and all of his friends when he was a kid.

This is so great, I needed a prop sword for a movie I'm making and this makes a great and safe way to shoot an epic battle scene. I've got my layers glued together and I'm ready for shaping. Do you have any tips on carving and shapping? I really need this to look great.
Dr Qui mcpoofy3 years ago
An electric carving knife if you have one, makes carving foam a piece of cake.  I worked in a hardware store that sold foam sheet cut to order, we used an electric carving knife as it cuts even 6" sheets of foam like butter.

If you dont have an electric knife a sharp kitchen knife with a serrated blade works ok
morfmir (author)  mcpoofy4 years ago
You can make some engraving with a soldering iron, put the tape a little lose on the relief and highlight the engravings with a marker. Make some tests on a scrap piece of foam to practice.

mcpoofy morfmir4 years ago
Awesome, thanks! I have a lot of small details that needed to be carved in th middle and I had no idea how to do it, Your soldering iron tip will work great!

Thats pretty cool! thanks for all your help, im gonna use that for my Halloween costume!!
smileys4 years ago
hmmmm.... I wonder if you could do a sephiroth style sword using this method.... better yet cloud's buster sword!!! Oh by the way if you can't tell I like final fantasy....

That could work but I see a length/weight issue with those two swords. You will have to put something pretty sturdy under the duct tape

 Good to see you are training the kids in the way of Awesomeness early.  Then when they are older they can truly be epic larpers!
seflynn anex4 years ago
i agree thoes swords remind me of the old larp swords in my group now we have new epic ways of makeing them
I'll be sre to use THIS instructable instead of the other one I found in another site! :D
Attamet5 years ago
I made one! the one on the left is mine, the one on the right is my brother's. The method here makes really fun swords that don't hurt at all! From now on I'm making all my swords like this.

hey i am wanting to make my own sword and im just wondering is it safe to say that ur foam is about 5mm thick?
morfmir (author)  evenstay25 years ago
The foam I use is 8mm. If you can only get 5 mm and you feel that the sword is to thin with 5mm foam, just use 4 or 5 layers til you feel it has the right thickness. /Thomas
thanks =)
justjimAZ5 years ago
You have done a very nice job with this. I have made many, many foam weapons for various purposes and am very impressed with your results here.
FFVIIBOY5 years ago
well since its suposed to look like Sting and also cuz its a tutorial on makin a sword id like to know if youd join my group the Fellowship of The Ring and put this on
PS i am seriously suprised that no one else made a group called the Fellowship of the Ring
maybye cuz its a straight rip lord of the rings like if you play world of warcraft and make a hunter named Lagolass then people call you a b****
just sayin

 The result is quite awesome. I would recommend against using bamboo for the core though.

When bamboo breaks, it produces sharp ends. Having already seen in LARP people with broken weapons hit once or twice before noticing, i'd use another substance

we often use fiberglass rod with floormat foam, and PVC tubing with Pipe insulation.

 what exactly does your runic it spells aitawimui but what does that mean?
morfmir (author)  craftsman5 years ago
It means "Ash made". The inscription is known from a lot of iron age and viking findings. The straight lines is not i's it is space. Some times in runes inscriptions you see lines as a divider of words but most times it is dots.

The Rune looking like F is not only A but it is also the symbol of the Ash tree. And my viking alias is Ash (Ask in Danish)

 That's pretty cool where did you learn all of this
the powah of the enterwebs can teach anything, cmon u should know that by now.
Great project and very good looking blade, man. I usually make mine with pipe insulation (see the image below. Not easy for kids, though), but I'll probably use the holiday season to try my hand at making a few weapons according to your model. Good work!

(changed the picture below per request)

 the hilt looks really good.
Thank you for this instructable, Morfmir! This design looks much, much more safer then my wooden swords. They also look better. I have one question: Where can I find that pipe foam? Google just gives me links to Pipe Insulation...
morfmir (author)  Biohazard11945 years ago
Glad you can use it. Yes this is very safe, I have no problems in letting my kids play with it with out any supervision.

The pipefoam I use here is from a sittingpad. But you can use pipe Insulation instead. The reason why I use this kind of pipefoam is only because I could not find pipe Insulation.

when does the shield come out
morfmir (author)  no swear-man5 years ago
next week I expect.

kewl thx

               P.S. I absoultly LOVE the sword
aborior5 years ago
This makes me smile.
i prefer galdiator style fighting. i use just a 1" di. broomstick handle and pipe insulation tubing, and foam pommel. they work great and are nearly indestructable.

Cant wait for the Shield!!
 Thanks so much for this!! I need to make weapons from the Vikings for Honors and because I don't have a large forge so this is perfect! Thanks for this again :D 
To be completely honest I first thought that the sword I saw in the thumbnail for this i'ble was a replica sword of sting that would be used as the template, not the finished product.  These look utterly fantastic!  Cant wait to try and get my younger cousins making blades themselves that way they have some safe swords to wail on one another with, instead of  the wooden ones they use now XD
Juklop5 years ago
Your swords are pretty awesome. I myself have been making some LARP boffer weapons but I use a totally different technique that can be seen in this tutorial. fanwar.com/making_weapons_mastercraft.htm

I will take a picture of my swords eventually.
Wow, thanks!! That's really cool. The kids in the last few pictures are really lucky to have someone to make them things like this... :D

I suggest that instead of cutting it folded (I find it less precise) that you darken your line. Then fold the paper in half so the line is inside. Finnally you should rub the paper with something hard. When you open the paper you will have another line that is simmetrically identical to the one you drew.

Thanks, I enjoy making this guides, glad you like it.
I think the warhammer will come after the shield.

This time I will have patience and wait for it to appear, I know it will show up soon when you, my subscribers, get the message.
