    I spent many hours sharpening my pencils in the K&E sharpener. Then
    Pentel came out with the.5 mm mechanical pencil and what a change.
    Like going from a slide rule to an engineering electronic calculator. 

    Which makes me think of the Curta pocket calculator I have. It was
    advertised as the first pocket calculator. For those of you who
    remember the old mechanical adding machines, the Curta is the same
    thing in a 2"round cylinder that looks like a pepper grinder. Every
    now and then I get it out just to hear all the gears grinding as I
    use it as an adding machine. The gears really whir when you do a
    subtraction. The dog gone thing drives me crazy. I want so bad to
    take it apart to see how it works. 

    Its been a long time but I think I remember that the K&E sharpener
    had a cone of sandpaper inside the container that did the lead
    sharpening. It was pretty coarse. I don't think the sandpaper will
    last long sharpening metal. 

    Might try putting your metal in a mechanical pencil and spin it
    around. If the K&E works it will leave the metal with a coarse
    finish. 

    I rotate my pins against a cut off wheel in the Foredom handpiece
    then hit it with ZAM on a buffing wheel in my Foredom. Its a pain in
    the ..... but works.
