I made this knife to show some friends how to make simple duck tape and cardboard weapons, and I like how it turned out. It's very easy, doesn't take much time and looks great.

Step 1: Materials
To make the knife you will need:
- Corrugated cardboard (most cardboard boxes work well)
- Duck tape, silver and black or brown
- utility knife or x-acto blade
- pen or pencil
- scissors (optional, I prefer to use a utility knife, because cutting it with scissors is difficult)
- sharpie (optional, I didn't use one)
Step 2: Drawing the Blade and Cutting It Out
I looked around on the internet for a picture of an elvish knife, and I use this one as a guide. Put your cardboard down on a flat surface and draw the shape of your knife (mine is about 12'' long), it doesn't matter if you have to re-draw it several times, the lines will be covered up. Once you're satisfied with the shape, cut it out and set it on top of the sheet of cardboard again, and trace it. I use two layers so the knife will be stronger, because once cardboard bends, there's really no way to fix it. Cut out the second knife you've drawn, and match them up to each other and trim so the edges to match.
Step 3: Covering the Blade and Handle
Match the knife pieces together, and cut or tear a small piece of duck tape, and wrap it securely around the middle of both. Continue the process, using smaller pieces for the curve and the tip. Once you've finished covering the whole thing, mark where the grip is going to be and cover it with black or brown tape.
Step 4: Finished Blade and Decorating
Your knife is finished, and if you want you can add some elvish script, designs, or dwarf runes to it to make it look like an authentic Middle-Earth weapon. I haven't done this to mine yet, but I've done it to other weapons and it's not hard. Sharpie does rub off over time so you might need to redo it every now and then. Go kill some orcs with your new weapon!
