    I rarely use pencils anymore - only for marking wood for carpentry. And then I use a pen[cil]knife. When I was a draftsman back in the 1960s and early 70s, I used mechanical pencils, either the kind that used 1/8" or 2 mm lead, or the 0.5 and 0.7 mm lead. As a kid growing up in the 50s, my grandparents had a pencil sharpener on the wall by the basement stairs - very much like this. I still have it somewhere:

    Many more types 1910-1919: https://www.officemuseum.com/sharpen..._1910-1919.htm

    There are also some that look like miniature lathes:

      Same here, and I still have the old Boston hand cranked model. My question is, where could I find some of the old drafting leads that came with the nice German compass sets? Yes I have some of those and still use them. Remember how they were in a tiny little tin can?

        The 0.5 and 0.7 mm lead came in prismatic plastic boxes. I think the 2 mm lead was in cardboard boxes. Here's a place to get some.

            I was interested in the difference between lead (graphite) and slate pencils, and found this on the history of pencils. The search also, surprisingly, came up with many references to eating, and trying to stop eating, slate pencils
