Mars Lumograph

I was curious about why my pencil is called Mars Lumograph, so I googled it, and I've discovered a whole new world of pencil appreciation. Have a look at pencil talk... The blog post is interesting, and I enjoyed reading the comments too. I'm not ready for the more extreme pencils yet but I might have to try an H and an HB as well as the B and 2B that I've already got.
