I teach 7th grade math and science. we use pencils....lots of pencils.
Lead pencils, colored pencils, etc.
My sharpeners crap about about every 4-6weeks. I'm toying with the idea of building the ''ultimate sharpener''.
I'm trying to get some input on a few things:
Motor: I'm trying to think of a motor or an object that would have a decent electric motor that wouldn't be horrible loud.
Blades: I'd like to be able to use the blades from my broken sharpeners. think screw down, boston-esque, spiral cutter blades.
i'd love for there to be a way to attach the spiral type blades to the motor fairly easily, build some type of casing to house it all, and flip the switch to operate.
i don't want to create a vortex that pulls kids into it (hmm.....) but i do want to be able to sharpen any type of pencil and i want it to last a while.
thanks for the input,
Matt
