Instructables

Step 1: Materials

Metal ruler
Filer/grinder
sharpening stones(one smooth and one rough)
wide string(sorry, don't know what it is called, just found it)
tape
wood
rasp
hack saw
hot glue gun and glue sticks

Step 2: Cutting the ruler

Picture of cutting the ruler
cut the top of the metal ruler so is on an angle.

Step 3: Create an edge

Picture of Create an edge
Use a grinder or filer to create the edge. i used a filer.The edge should be 25cm long. '
Furthermore, the edge created by the filer should be already quite sharp.

Step 4: Removing the measurements

Picture of Removing the measurements
I used a small filer of mine is placed the tip agaisnt the ruler and filed off the words.
After the words have been removed, feel free to sand the blade so it is smoother.

Step 5: Sharpening the edges

Picture of Sharpening the edges
First use the rough sharpening stone to sharpen your blade. After the razor sharpness is acheived, move onto the smoother stone.

This is a link to how to sharpen the blade :

You may have to repeat this process more than what it actually tells you to do.

Step 6: Handle

Take too peices of wood, about 13cm x 2.5cm(its your choice on how long the handle is).
Rasp the edges of the peices of wood so it is round.
Now, put the peices to the blade with. The blade is in the centre and 2 peices around it. You should find that the handle is bigger than how much metal that is provided by the blade itself.
After it had been glued, i filled the gap up with some spare metal i had, you could also do with cardboard.
I linseed oiled my handle later on to acheive a nicer colour.

dude that looks more like a ninjato to me great idea
No. You obviously know nothing about the ninjato. A ninjato/shinobigatana is a wakizashi-length blade mounted on a katana koshirae.
He's right.
Who's right? Me or him?
You XD

Ninjato has completely different hardware, blade length, and style!!

you wouldn't have to use a metal ruler if you didn't want to hurt anybody with it.
I think it's very obvious that he does :P That or he did use that thing as a Machete.

i used a filer to obtain an edge. Afterwards, i used a sharpening stone that was rough and a smooth one

thats sick is it quil with the file and does it need to be asharpening stone or just a rough stone
my_2_cents (author) 6 years ago
hehe, i had the measurements on the handle too. The machete now looks different, i will update it later. i removed the grip because i instead linseed oiled the wood. Im working to engrave my name on it so it shows i made it.

Simply awesome, but I would probably leave the measurements on down by the handle so people know I made it.

i made it for coconut cutting =.="

the blade is not very flimsy. Some cheap metal rulers are flimsy and some are quite stiff. Mine is actually not flimsy but not the very stiff. It works though.
@smart Was going to but tourch had no batteries as well =P

Nice, I have that ruler :P I like the design of the handle, it looks like a samurai sword handle, Maybe next time shine a light on your project so it it brighter :P

And this also makes a lovely shank for those of you that are currently guests of the prison systems in this great land of ours. PS: A much better blade can be made by using a discarded file as bar stock.

Metal rules are flimsy so this would be too. Flimsy swords/knifes/ruler-swords arent good? Its a good instructable though, Machetes are fun
Im sorry, Metal RULERS***
Nice work, but u forgot to mention I did half of it
my_2_cents (author) 6 years ago
thanks guys. my camera's batteries are out and couldn't be bothered recharging them so i took the pictures with the webcam, hence, they are crap. I was initially going to take them with a phone but i couldn't find the cord to connect it to my pc
shooby6 years ago
I don't think this is a machete. I do know for sure that you can buy a machete for the same price as some metal rulers.

Great job! I've been wanting to try knife making for a long time. Did you take the pictures with a phone?
Looks like a low-quality webcam. Most phones take portrait-oriented images, don't they? These are 320x240.
