This pencil sharpens itself

Why hasn't anyone done this before? This pencil has a sharpener built right into it, allowing you to use it with the comfort that comes from knowing that you'll never have to hunt around for a sharpener if you break the tip by accident. Just pop the sharpener off the back, use it, and you're back in action. Who says innovation only happens with the latest and greatest gadgets?
