But back in graduate school, I noticed that mathematicians (including myself) universally used mechanical pencils. Easy to write with, easy to read, easy to erase and write over, and no sharpening. :-)
Out of habit I continue to use mechanical pencils even though there isn't much difference between them and anything else for my current needs.
