This sharpener does not sharpen the pencil, disassembly will be necessary to fix it. This video can give you a better idea of how a battery-operated pencil sharpener works and how you might approach the problem to repair it. Be careful with the tools you use to repair it and with the blades of the pencil sharpener. If you do not have experience fixing things or do not have the appropriate tools, never attempt to repair any device or object that is broken. This video is for demonstration purposes only.
