I have a case of #2 pencils and need to have them sharpened. Is there a service you can recommend? While I am picky about how my pencils are sharpened, I have no formal training in doing so. From time to time I wind up with a pencil that was cut off-center and I have to compensate, but it's so rude to try to nick off that last bit before I bite into graphite. Unwieldy.
