Introduction: Penny Knife
Welcome back! I have just made a small knife out of a penny! It isn't good for much more than letter opening but it's still pretty cool! This may be illegal where you are though it isn't here cause Canada doesn't have penny's anymore. Let's get into it. I also made a video! I will make one for all my coming instructibles! So make sure to subscribe! https://youtu.be/QCSlhZ5Kta4
Step 1: Marking and Drilling
Glue all of the penny's together then mark three dots about where I did. Then drill with a 1/16 drill bit on those holes. Use a drill press but if you don't have one then you can use a normal drill bit the bit will probably break. Since mines broken I can't show the drilling.
Step 2: Cutting the Penny
Next you need to disconnect the penny's from each other once you have all the pennys apart you need to cut the middle one down the center so that one hole gets cut off. Remember what holes line up to each other
Step 3: Cut the Blade
You can cut the blade out of a shingle cutting razor blade. One of the curved ones cut it and grind down so that it fits into the half penny. Also grind the back so it's round and can fold.
Step 4: Add Pins
Then you can add copper wire as pins to hold it all together. Just push them in and cut them. Then hammer them down so they are flat.
Step 5: Done!!!
