Marketed as the "world's first chuckable drill powered pencil sharpener", C.H. Hanson's $US7 Pro-Sharp Finishing Pencil Carpenter sounds much more scientific than it actually is. Just attach it to where you'd normally screw in the drill bits; whack a pencil in, and zooooooooom, off you go to sharper-pencils nirvana. And breathe!
Using a CD jewel case, some magnets and a 12-volt air compressor, you can build an elaborate Tesla turbine sharpener for pencils you probably don't even use. Oh, did I mention it could kill you?
