Oh look, your stranded in the middle of the ocean and your only pencil just broke. But wait! You have that knife that just magically appeared on your hands! And you are just now receiving enough phone coverage to view this instructable! Great! Let's get started.
Step 1: Supplies
Here are some useful tools to sharpen a pencil.
1- A knife- You can sharpen it with this!
2- Two hands- Very useful in the process
Okay, putting the very bad sense of humor out of the way, let's get on to the actual process!
Step 2: Sharpening
First, hold the pencil in your weakest hand. Then grab the knife in your stronger hand. Now take the blade of the knife and start at about 3/4 up of the pencil and press with the knife. Pressing down, slide the pencil to the tip, still applying pressure. Continue this process, rotating the pencil just a bit each time.
Step 3: And Your Done!
That wasn't too hard, was it? Now go off and write more about your journey at sea!
