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

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.

    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.

    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)

    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? )

    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.
