USB-powered pencil sharpener

There has been plenty of USB peripherals over the years with some bordering on the ridiculous, but there has been some gems as well. The USB-powered pencil sharpener is useful in offices where most pencils have mostly blunt or broken tips and there is no manual pencil sharpener in sight anywhere. What better way to get your graphite pencil going again than to give it the USB pencil sharpener treatment? It stops and starts automatically, so there is no need to worry about how sharp your pencil could be. The $10 iSharpener can be powered by 3 AA batteries or via USB.
