Introduction: Metal Ruler Into Small Machete

Picture of Metal Ruler Into Small Machete

This machete is made from a 30cm ruler i had. It is stainless steel hardened

Step 1: Materials

Metal ruler
sharpening stones(one smooth and one rough)
wide string(sorry, don't know what it is called, just found it)
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

Picture of 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.

Step 7: Grip

Picture of Grip

The handle is done, this is optional. I did the katana grip with my wide string. Here is a tutorial on how to do the grip :

After that is done, put some electrical tape below the grip.

I also added a chain to the bottom of my handle just for the looks.

First i got some corrigated cardboard and cut it to the shape of the bottom of the handle

Then, with a chain, i cut it in half so one is in half.

Now, glue the peice of cardboard to the bottom of the handle. Then take the half chain and push it into the middle. This is just to make the holes. If you didn't get a hollow hole, use a knife to do so.

Now, take the rest of your chain, the desired length and put it into the half chain.

Finally, simply glue the half chain into the holes that were made earlier.

I then coloured the cardboard black with my permanent marker.

Step 8: All Finished!

The small machete is done.

i take no responsibility with what you do with this...

Is it strong enough to stab? Its just metal ruler. I've made dozens of them so I know. Next time, make it shorter or join two piece of metal ruler together to make it stronger (friendly advice) . By the way, your tanto is beautiful. I like your decorations.

I love the dragon ball z posted in the background haha

I made one of these to commit seppuku with, but decided to just live with dishonor instead. good instructable I like the handle.

Hari-karidiculous Ha-ha!

lol. thank you :D

blah424 (author)2010-12-29

this looks like a sick half katana half machete thing

sonicsanti (author)2009-04-21

dude that looks more like a ninjato to me great idea

Camisado (author)sonicsanti2009-04-29

No. You obviously know nothing about the ninjato. A ninjato/shinobigatana is a wakizashi-length blade mounted on a katana koshirae.

Pumpkin$ (author)Camisado2009-12-03

He's right.

Camisado (author)Pumpkin$2009-12-04

Who's right? Me or him?

Pumpkin$ (author)Camisado2009-12-05

You XD

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

my_2_cents (author)Camisado2009-12-04

you i guess, lol

your "wide string" appears to be plumbers tape

no, its some string my mum used to use :D

oops looked like it in the pics lol

cheezpocket (author)2009-05-31

crayzclown1 (author)cheezpocket2009-09-15

my_2_cents (author)2009-05-21

activescout (author)2009-05-19

strmrnnr (author)2009-05-17

Did you try any heat treatment with the kives you make from rulers. I am wondering how they turn out.

gage.overton62 (author)2009-04-22

my_2_cents (author)2009-02-16

What for? The Machete is now given away to my friend for hes birthday. he used it to cut the cake xD

Aklash, The hunchback (author)2008-11-15

this is genius, why didn't I think of this?

pyrocreater (author)2008-11-01

mine can cut through an apple=)

randomguy96 (author)2008-08-06

you wouldn't have to use a metal ruler if you didn't want to hurt anybody with it.

Camisado (author)randomguy962008-10-22

I think it's very obvious that he does :P That or he did use that thing as a Machete.

sniper1 (author)2008-10-20

thank you very much aramaru it's ppl like you that keep the world turning thanks

sniper1 (author)2008-10-06

dose anyone know any website i can go to or can tell me how he tied the string on his handle

Aramaru (author)sniper12008-10-19

when you tie the wrap twist it

my_2_cents (author)2008-09-26

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

ardo6969 (author)2008-09-26

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)2008-09-06

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.

RockInBlack (author)2008-09-06

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

my_2_cents (author)2008-08-06

i made it for coconut cutting =.="

my_2_cents (author)2008-06-29

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

=SMART= (author)2008-06-29

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

Phoghat (author)2008-06-29

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.

NeonLime (author)2008-06-29

Metal rules are flimsy so this would be too. Flimsy swords/knifes/ruler-swords arent good? Its a good instructable though, Machetes are fun

NeonLime (author)NeonLime2008-06-29

Im sorry, Metal RULERS***

DuctTapeRules! (author)2008-06-29

Nice work, but u forgot to mention I did half of it

my_2_cents (author)2008-06-28

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

shooby (author)2008-06-28

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?

CameronSS (author)LinuxH4x0r2008-06-28

Looks like a low-quality webcam. Most phones take portrait-oriented images, don't they? These are 320x240.

codester (author)2008-06-28

That is so cool! Great Instructable. I love it! I'm definetly trying this out today!
