We homeschool, so we need to sharpen our pencils a lot. Our pencil sharpener broke and now we need a new one. I like electric ones that plug in but would also consider a manual. It needs to be quiet and not messy, it also needs to not break the pencil tips easily. How much did you pay for your pencil sharpener? Was it worth the cost? Has it lasted a long time? How much do you use it?
