I’ve recently rediscovered that I have several Staedtler non-photo blue pencils. These guys are great for beginning your drawing and creating construction lines. After that, I don’t have any particular preference with pencils, although I tend to like harder graphite as opposed to soft. Less smearing. I do have a Pentel .5mm mechanical pencil, but traditional pencils work just fine, too. Eraser pens are a must when working with graphite.
