How Dose a Pencil Sharpener Work??

Akayla  week 4 term 2

WALT:To write how a pencil sharpener works.
  • Write out my point of view
  • Research how it works
  • See how it really works and what makes it work
  • Best kind of sharpener to use

A pencil sharpener works from its sharp blade, you insert your pencil into the little hole that it has and then you start turning your pencil and as you can see from this picture, some carved wood comes out after a while of turning your pencil you pull it out and it should be sharp.

All pencil sharpeners work pretty much the same way. A pencil is placed inside a hole in the sharpener where there is a sharp metal blade tilted at a special angle. This angle will give the pencil its pointy shape. The blade is actually able to shave off the wood and graphite of the pencil until the pencil is ready to write!
In some small box pencil sharpeners, you use your hand to turn the pencil against the blade. In wall-mounted and desk-mounted pencil sharpeners, we hold the pencil still and turn a crank that spins the blade around the pencil. In electric pencil sharpeners,  hold the pencil still while a motor spins the blade around the pencil,
Once your pencils are pointy and ready to write, remember to be careful because they are very sharp!
