CMV: Pencils are Superior to Pens

To begin I feel that we should compare high quality pencils with hiqh quality pens so as to appropriately evaluate the best of what each form of stationery can achieve.

I've personally found that modern graphite technology can allow pencils to reach the same intensity of colour/black as most pens whilst still allowing the user the opportunity to erase and change what's been written. Alongside proper quality paper stock high quality pencils can also glide just as smoothly as high quality pens whilst, from my left-handed experience, setting faster and therefore smudging less.

* Pens are permanent. They can't be erased. This is an ideal quality for signing legal documents.

* Pens can be refilled with more ink. They are far more durable than a pencil.

* Pencils become smaller as you use them. Pens remain the same size throughout use.

* Pencils require an extra tool called a sharpener. Pens do not need any accessories.

* Pencils change from sharp to dull. This variability affects the way they handle and the way their markings look on paper. Pens are consistent. 

* Pencils need regular sharpening, which is a tedious process. Pens do not require any upkeep except for ink refills on a very infrequent basis.
