How do I sharpen my pencil sharpener blade?

You can do either. If you're learning you should start out on the ground and transition to the air. Build up your leg strength to make it easier.

It depends on your skill level. You'll want to start out slow and work your way up to going fast.

Yes. Having a concealed carry license does not get you past the state laws concerning knives. Most states have laws concerning the length of blade you are allowed to carry...

Yes it's a possible replacement. Try using different colored blades.

You can find X-Acto blades at any of your local hardware or craft stores.

A chapstick would be very difficult to turn into a pencil shape and it is very unlikely that you'd be able to color it. It also wouldn't have any graphite...

It most likely is durable, but it mainly depends on the width and flexibility of the metallic ruler.

Stop using so much muscle. Let the saw do the work while you power it back and forth, not down!

Possibly, but only use a handheld one as it could wreck any other. Try it out and see if it works.

Use the same method as the shovel (with a file) and finish with a grinding stone.
