Pencil mounted self sharpening pencil sharpener   (+7, -1)  [vote for, against]
built into your pencil, sharpens itself.

An ordinary wooden pencil is made to be self-sharpening, through the addition of a discrete grip-sleeve where you hold it. Concealed in the grip sleeve is a blade, which, at the press of a button, extends at exactly the right angle.

Holding the pencil and twisting the grip sharpens the pencil.

As the blade retracts, it passes over a small yet pefectly angled shard of whetstone which keeps it at optimal sharpness.

The whole kebang is, needless to say, transferrable from one pencil to another.

Pretty sure this is a pencil sharpener. The sharpener has a built in sharpener, too, but it isn't sold separately.

Also, the way you titled it, one would be led to believe that your pencil sharpener sharpener is made out of pencil which is both false and blindingly stupid.

May I suggest "Pencil sharpener sharpening pencil"? Have some hyphens to spread around as you wish {--} <==(not fishbones)

not sure how grips come into it: your title indicates a pencil made out of whetstone which is inserted into the sharpener and rotated in the opposite direction.

OK, I submit; silly title changed.

Could we mount a pencil sharpener within somebody's facial hair, a moustache for example?

I often wondered how Edwardian villains kept their moustaches so impeccably pointed. Now it becomes clear to me - pencil mounted moustache sharpeners.

//pencil mounted moustache sharpeners// One wonders if they could be arranged within some kind of planetary gearing mechanism, so both pencil and moustache can be simultaneously sharpened?

An idea is forming, not yet even half-baked, for a Universal Sharpener, which will simultaneously sharpen everything with a single wrist movement.

Wow, you have an infinite depth of field? In which case isn't the focus knob redundant?

so its also a pencil sharpener sharpener and also a pencil pencil sharpener.
