Introduction: Binder Knife

Picture of Binder Knife

A very sharp knife made from a binder

Step 1: Step 1

Open the binder and take out the part that holds the paper without bending it. Then when you have it off flip it over and you should see two strips of metal (the bigger the binder the bigger the blade and it will be stronger). I used a fore inch binder for this. Try to take the metal strips out without scratching them up to much because it will be harder to polish if you don't have a polishing wheel. When you have the two strips out they should have three rings in each strip, when you are at this point move on to the next step. SORRY I dont have a pic for this step :(

Step 2: Step 2

First cover your pliers grip with paper so that it won't scratch the blade. Then push the half loops back out of their holes. This might take a while to do.

DO NOT CUT THEM OFF!!!!!!!!!!!

Step 3: Step 3

With a pair of tin snips or a pair of scissors
(tin snips work the best) cut tip to be on a 45 or more angle I did a 45.

Step 4: Step 4

Picture of Step 4

To make the handle use wood glue to glue 2 popsicle sticks to each side of the blade( the popsicle sticks should cover about 1.5-2.5 inches of the blade). Then clamp and let dry over night. After it is dry wrap it in grip tape and then you are done the handle.

Step 5: Step 5

Uses a metal file to do a rough sharpen. Then use a sharpening stone.

Step 6: Step 6

Use a polishing wheel or a polishing stone to make it shine.

Step 7: Step 7

Now you have a finished knife. If you need a sheath than take poster board cut it to length and then wrap it around the blade 4-5 times and than cover it with tape then you can paint it.

 Nice Newton's cradle in that picture! I love those things!

This my binder knife, It's short because I used the wrong part and had to break it, ut it is a pretty good knife. P.S. I didn't have a sharpening stone so I used a Metal File P.S.S. The sheath is cardboard wraped in a cord.

haha niice looks good!

NinjaFreak102 (author)Pat Sowers2009-09-25

do u think that a binder sword made of three layers would hold up good

Pat Sowers (author)NinjaFreak1022009-09-25

honestly no. i meen give it a shot but it wont be that good.

zany (author)2008-07-19

here is a partly unrelated comment. sorry. i am 15 and don't have a forge, polishing stone, or whatever, and one of my parents is at home pretty much of the time. is there still any way to have a knife or sword? (besides a binder knife-the binder knife was really good though. ty for the instructable)

i know everyone else is posting stuff like this so, ive grown up with knives and stuff, throwing them choppin sht and all that yeah i dont really understand your question

this is a cool idea btw, this instructable

Wow, your parents don't trust you with knives and you're 15 already? Wow.... that must suck. I'm a couple of years younger than you and I start collecting weapons when I'm 9. LOL. I'm trusted with a knife when I'm 8, also got my first wooden sword and a dagger. Got a shoto sword off the internet when I'm nine ( this is when I started collecting weapons ). Weapon collection has been growing rapidly over since. Heck, even got my own storage of weapons! ( If you don't believe me, take a good look at my avatar. The Katana on my back is family heirloom, and the Tanto knife is made by me. Cool, eh? )

zombiehunter96 (author)Camisado2009-09-03

Yah I got my first gun which was a savage arms 22. bolt action long rifle when i was 7 or 8 for christmas and now i have my own collection of guns. I started makeing and collection melee weapons when i was 6 or 7 and have a nice collection. PS. I make weapons out of everything is see, today my dada gave me a pair of fingerless gloves and im putting spikes on the knuckles! Should be sweet.

hahahah nice!

Pat Sowers (author)Camisado2008-08-22

Camisado (author)Pat Sowers2008-08-22

whata you need help with?

truckersson9 (author)Pat Sowers2009-03-21

Well i dont understand how to get the rivets out and what is the blade? reply

Pat Sowers (author)truckersson92009-03-21

the blade is the strip of metal that the rivets are in. to get the rivets out get two pairs of pliers. take the one and hold the blade as close to the rivets as posible. then take the other and hold the rivet pushing and wiggling it till it comes loose (this takes a lot of force) once its loose you should be able to take it out.

inzanegunz (author)Pat Sowers2009-08-17

i need help badly, could you post a instructable about how to get rid of the rivets?

truckersson9 (author)Pat Sowers2009-03-22

Thank you very much.I get it now . Have A Nice Day!

Pat Sowers (author)truckersson92009-03-22

no problem. and you too!

sdfive (author)2009-06-30

I think ill smith a bunch of these together and make a sword. I'll tell you how it goes this will be my first smithing attempt.

jake walker (author)2009-06-08

i took apart the binder but have no way to sharpen and i can't invest in a sharpening stone. any ideas?? thanks

learntodostuff (author)2009-05-05

what metal strips? are you using both strips for this project or only one? Please send me a pic.

only uses the one. its the metal strip that the half rings are attatched to

you mean the metal strips that helps the rings open and close? if that's what you mean then why do my strips not look like yours, they look skinnier than yours?

cdizzle (author)2008-07-08

how did you get the rivets out

Pat Sowers (author)cdizzle2009-03-07

the way ive always done it was by taking two pairs of pliers. hold the blade as close to the half loop as posible and use the other the wigle it out.

Picothellama (author)2009-03-07

pleeeeease answer cdizzle. i have the same problem

liberals arent anti knives hell many of us arent anti gun i personally think they should stay because they are a right given for protection from the goverment until a less violent way of killing the large majority of the govement for non govermental takeover arises i like guns although come to think of it youd need a fairly large army to actualy try and alot of suicidal people how hate america any way knives are a tool you cant prepare food with a gun or a lot of things no actually most anti knife parents a rebos who need to "protect their kids from them evil liberals whom dont believe in god ... eww it makes my blood currdel" not saying all rebos are like that but most liberals dont mind what their children do to a level

I'm a liberal(like the rest of my family) and my mom (also a liberal, duh) is not real big on knives too. personally, i think knives, guns, and we cannot forget swords, are great. but unless under very specific circumstances, they should not be used to maim anybody.

NCRatSniper (author)2009-01-13

Wow, this is so ghetto it's awesome. I remember making blowgun darts out of thin binders when I was a kid. didnt look very nice though. Good ol days of shootin starlings,sparrows, and rats.

Pat Sowers (author)NCRatSniper2009-01-13

hahaah nice dude

z-man6233 (author)2008-11-04

lol i was board so i took apart another binder and made a folding and throwing knife

Pat Sowers (author)2008-10-11

ahhaah yeah i know right. my swords and knives i forge are godly. but this is good for a little binder knife. it gets the job done for some people. now my knife omg thikest thing i cut was just shy of 2 inches with a 4 inch blade that thing is freekin sharp as hell.

flamerz14 (author)2008-04-02

COOL. now i finally got something to do with all those binders at home...

minfu2 (author)flamerz142008-04-11

It is so hard to get the 2 metal striips out. I almost cut off my finger. The thing binder edge was sort of rusty, so do you think I am going to get tetanus or something?'

thoraxe (author)minfu22008-10-11

i heard its false that rust will give you tetanus. It just so happens tetanus like to live in dirty places, and things that are rusty are usually dirty

Pat Sowers (author)minfu22008-04-12

did you lose blood? and how rusty was it? and when was the last time you got a shot?

minfu2 (author)Pat Sowers2008-04-24

i'm not dead or rabid yet so i'm probably fine.

Tetanus shots are kinda like batteries: Once you use it you need to refill it. Or so my doctor tells me....
