Before school started, I bought one of those old fashioned manual pencil sharpeners that clamps to a countertop and has a handle you crank. It broke on day one. I bought a mid-range electric sharpener, and the motor burned out in a week. Since then, I've just kept buying the little ones that look like the sharpeners you use for eyeliner. Those are the best so far, but they take forever when several students want to sharpen pencils at once. I think I'm ready to quit buying cheapies and invest on a durable, quality sharpener. Any suggestions?
