Some way of sharpening the knife

Although this knife is not a super high quality knife and it cannot stab things very well, you can make it very sharp and it is just as good as cutting as my other knives. Plus, it is a fun project to do with your(teen) kids. It's not hard, and it only takes 1-3 hours so you can do it as a weekend project. So without further ado, let's get started!

*DISCLAIMER*

Knives over a certain length may be illegal in your state, so check the restrictions before you make this.

When choosing the pipe, make sure it is steel. It doesn't have to be too thick, but it can't be microscopic either. Remember, the thicker it is the better the knife is going to be, but the harder it is to work with. And too thick won't come together enough. As for diameter, as big as you might want!

Mark how long you want the knife to be, handle and all.

Grind the section right above the mark you made on a bench grinder all the way around and either just break it with your hands or push it against the corner of a wall.

Grind away the extra metal using a bench grinder.

Now mark how long you want the handle to be and pound it down as thin as you want it on an anvil or and the back of a bench vise.

Pound the opposite section of the blade until it is as thin as you can make it. Make it as thin as you can possibly make it and make sure you get the edges really fine.

This step is optional but useful. You can make a handle out of anything you want to(I made mine out of the grip for a tennis racket), baseball grip, tennis grip, duct tape, or any other material you want to use.

Grind the knife to the shape you want it using a bench grinder but make sure as you are grinding it, point the blade down. This step might take a while so be patient with it. You can also polish the knife in this step.

Sharpen the knife. You can use any technique available to you, but before you do anything else, run it along the grinder moderately fast so it already has somewhat of an angle. And remember to grind more off one side. I then sharpened mine by running it through a smith's sharpener as hard as I could so the blade conformed to the angle of the sharpener and I can now use the sharpener on the knife.

At this point, you are done! congratulations, and hopefully your knife turned out as well as mine!
