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.
lock and key is the lever of second type
ummm absolutely none its just wood with graphite inside i think you haave got a bit confused....

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.
