A pencil can be considered a Class 3 lever, with the hand providing the effort, the pencil acting as the load, and the fulcrum being where the hand grips the pencil.
No, it's a compound machine.
A pencil sharpener is a compound machine made up of simple machines, like the screw and lever.
A mechanical pencil is a Class 1 lever. The writing tip serves as the fulcrum, the effort is applying force on the pencil, and the load is the lead that is pushed out.
A pencil sharpener is an example of a simple machine known as a wedge. The blade inside the sharpener is shaped like a wedge, which helps to cut and shape the pencil tip when it is inserted and rotated.
A pencil sharpening blade is not an example of a lever. Levers typically consist of a rigid bar or rod capable of rotating around a fixed point called a fulcrum to lift or move objects. The pencil sharpening blade does not function in this way.

SCISSORS ARE WEDGES WITH A FULCROM so that mkes thm both
The pencil is the same type of contribution as the waterslide.
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.
A pencil sharpener is a type of inclined plane simple machine. The blade inside the sharpener is positioned at an angle to the pencil, allowing for the application of force over a longer distance to produce a sharp point. As the pencil is inserted and turned, the inclined plane of the blade shaves away the wood and graphite, creating the pointed tip.
ummm absolutely none its just wood with graphite inside i think you haave got a bit confused....
