A pencil isn't a lever at all, unless you are using it to turn force into useful motion. If you use the pencil to write with, it's closer to being a needle reading a record, as it is dragged across a surface, leaving graphite which has broken off of the main core on the paper. For a first class lever, think of a see-saw. For a second class lever, think of a wheelbarrow. For a third class, think of a pair of nail clippers, or of your forearm.
