Here is how to make a throwing fork. I made this up. I hope you enjoy.
Step 1: Flatten Your Fork
First you need to find a old fork and flatten it. Look at pictures for more detail.
Step 2: Cut Your Fork
In this step you will cut two prongs off the fork. Look at pictures for more details.
Step 3: Shape Your Fork
In this step you will shape your fork and get a edge on it.
Step 4: The End!
You can throw this into cardboard and even into wood, if you trow it hard enough. Hope you enjoy.
