Introduction: How to Make a 6 Cent Pocket Knife

Dont Forget to Vote!



Here's what you need:
-Nickle
-Pennie
-Hammer
-Vice
-Hack Saw
-Grinder/Polisher
-(Optional) Cold Metal Blueing Agent

Now lets get started


IT'S LEGAL! U.S. Title 18, Chapter 17, Section 331: Prohibits among other things, fraudulent alteration and mutilation of coins. This statue does not, however, prohibit the mutilation of coins if done without fraudulent intent if the mutilated coins are not used fraudulently.

Step 1: Hammering and Cutting the Nickle

In step we will hammer and cut the nickle.

As you will see in the first picture, I simply just hammered one side of the nickle. This gives you a longer blade.

Then we start cutting. Get your pen and draw out your pattern, it should look something like the second picture below. Now take out your hack saw and start cutting, a few drops of oil can make the cutting process much easier. Be careful not to make the little bar hanging off of the nickle too thin, its what we are going to wrap the penny around, and we want it as strong as possible.

Once you get your nickle cut out, click on the next step to learn how to put the penny on it.

Step 2: The Penny

We are going to use the penny as a handle for the knife. I recommended using a post 1982 Penny if you have access to the Blueing Agent that I had recommended. This is because all pennies after 1982 are Copper and Zinc, and we can blue the zinc, which looks very cool on this knife.

Once you have your Penny put it in your in vice and start closing it until it starts to bend like in picture 1.
Then get your Nickle, and put the handle that we were talking about in the bend of your penny like in picture 2, and keep and closing it and SQUEEZE as hard as you can until the penny is completely wrapped around you penny, like in picture 3. You can get a hammer and hit were to 2 sides of the penny meet, to make sure it wont fall off.

Right now your knife looks like a dented up mess, but in the next step we will clean it all up and make it beautiful and sharp!

Step 3: Grinding, Polishing, and Sharpening.

In this step we will grind, polish, and sharpen your knife. Get a very abrasive grinder and shape your knife to how you want it. You can get creative here, but keep in mind that it needs to be strong, so don't make it too skinny.

Then get a medium abrasive grinder and start grinding away the copper on your penny (that is if you are using a post 1982 penny, if you are using a pre 1982 penny, just grind it down until you cant see the face anymore), This is also a good time to clean up the blade and make it nice and smooth. Then get your polishing wheel and give you knife a mirror like finish.

Once you are done with all that its time to sharpen your knife. You can simply do this with a belt sander.

I apologies that I did not go into further detailing on how to grind, polish and sharpen you knife.
This is because there isn't much to say about it. It is very easy to do, So if you have any questions about it, just ask!

Step 4: Blueing and Finished Product!

If you choose to use a post 1982 penny get your blueing agent and blue the handle.
I like to dip a Q-Tip into it and use it as a paintbrush.

And now, you have your finished product!
A cheap, cool looking, easy to make, pocket knife!

If you have any questions to be afraid to ask

it actually is tampering us currency is illegal

author

It is not illegal. If you actually read what it said you would've know that it isn't illegal. What is illegal tampering with coins as A FRAUD. Like making a penny look like a quarter. That's a fraud you can do whatever you want to do with the coins you have, just not anything involving fraud.

author
i_build_stuff (author)2009-02-19

awesome im going to use a quarter for this though.and im pretty sure destroying coins is not illegal but destroying paper money is and so ids defacing it like taking a $1 and puting a B before the ONE and a R after it so it says boner. but really no one is going to chase you for it even if it is a crime : / Canada needs to shut its mouth jk but seriously shhh :P

Destroing coins is illegal

author
sleeepy2 (author)C chord2014-07-23

Even when the Instructable cites the reg saying it's legal, we STILL get some posting saying it's illegal!

author
raven0811 (author)C chord2010-04-17

it is perfectly legal to melt down the old all copper pennies, why not bend them?

author
temp (author)i_build_stuff2009-02-26

I'm pretty sure it's only illegal if you cut the money into little pieces then try to spend it, or cover it in paint then try to spend it.

author
BERTBOY13 (author)temp2009-06-26

it may be illegal but I've never seen anyone police running round trying to arrest somebody for cutting a coin up. therefore i would say lets do it anyways!

OH GREAT! Now we won't be able to bring change onto an airplane. What will the NTSA do with all that change they collect at the entrance to security? Maybe they could set up a jet fuel fund for the public before coach flights from SF to LA get to $1000!

ummmm... you wouldnt be taking the machines on to the accessible part of the plane at least.

Does that work and cut

author
Chikpeas Brother (author)2013-07-03

I don't understand how you connected the two coins.

author

its not even a knife its a sharp sort of round thing

author

If you think about it, that's what a knife is, more or less.

author

actually that looks about the right size for a mouse slasher movie.. or mabye to skin a hamster with.

author
mykmykmykkk (author)2009-07-16

cool, but is it sharp?

author
cdawg14 (author)mykmykmykkk2009-07-20

That depends on how well you sharpen it.

author
punkhead58 (author)cdawg142010-07-12

Actually, it depends on the hardness of the blade. In this case, since the blade is composed of copper and nickel, I doubt that it will hold an edge.

author
seabee890 (author)2010-04-30

You, have caused my mind to start winding up.... the change jar will be ruined..  hehe, i was just thinking how about a "silver"dollar coin for the blade and a mexican 100peso coin for the handle, that would give you a bigger knife. I am also trying to remember if you can you some flux and silver solder to fold your nickel in half and draw it out to make a longer blade. cool instructable though. enjoyable

hmmmmm..... that's weird because it's comments like this that make people less likely to even care or notice :D and if a person named PyroManiac96 is going to diss me about being a proud american who was indeed born on the fourth of july he should at least realise that there is a flag option and I find you rather myself threatened as a patriotic citizen of the United States of America

About the penny pressing machines: this summer while in Quebec City I stopped by one machine that said to not use Canadian pennies. The notice said that there were American pennies available at the desk. There are some machines that how supply brass blanks automatically.

author
bmlbytes (author)handidad2008-09-11

I saw the same thing while we were visiting Canada. The reason for this, I believe, is that American coins are made of a different material than Canadian coins. If you ever hold a Canadian coin and an American coin, you will notice that the Canadian coin is much lighter (quarters are the easiest to tell the difference). On our way back to the USA, we saw one of those machines that supply the brass automatically, only the "blanks" were a bunch of US pennies.

canadian coins are iron with copper finish. they will respond to magnets. this is another sign of proof that the gov't is wasting all of out $ on purpose. did you know that a penny is worth 18cents when melted down? ouch

author
zazukain (author)klingonprins2009-09-01

Not anymore, pennies after about 1970 have a copper finish.

author
klingonprins (author)zazukain2009-12-01

yeah, i meant that...
no i meant really the amount of copper in the shape and size of a penny would be.

author
handidad (author)klingonprins2008-11-11

Your comment is only partly true. I dug out a handful of change, all Canadaian.. Althoug they are mgnetic, I doubt if the copper is simply a finish, more likely an alloy of some sort. 4 pennies: 2007, 2005, 1977, all non-magneric. Only the 2008 was magnetic. The nickels, dimes quarters, loonies, and the outside part of the toonie were all magnetic. Probably 50 year old coins would have a different composition.

author
jeffconnelly (author)handidad2008-12-01

yeah, I found pretty much the same thing, but my 2005's were also magnetic

author
handidad (author)bmlbytes2008-09-11

It is quite possible that a brass blank would cost more than a penny. I have used Canadian pennies in these machines.
