multi-color mechanical pencil....
Does anyone make a multicolor mechanical pencil? Like the old 4 color
bic pens in a pencil? Rob |

I tried to arrange one of these by asking if I could buy a couple more of the little pencil mechanisms they make for the inside of a Rotring 600 tri-pen, because they seem to be made to fit into the same size opening as the little pen refills. The store here told me they weren't available separately at that time - but maybe you could get them somehow. I don't know, but I assume there are other multi-pen-&-pencil gadgets that are built in a similar way. Note: All the coloured leads I've seen are 0.7 or bigger - I think the 0.5 and smaller sizes break too easily and so are not made. David |

Pentel does make 0.5 red and blue leads. I tried using them when I was working
as a book editor, but there are a few problems. As stated below, they are indeed very soft and were constantly breaking--even the 0.7 sizes aren't that strong compared to black lead. But also, whether 0.5 or 0.7, they are very difficult to erase, which kind of goes against the rationale for using pencil. I've always wondered why the properties of colored lead can't be made comparable to black, but I suppose there's a good reason. I can't remember the manufacturer (it might have been Pentel), but I did once buy a multi-color mechanical pencil that had about a dozen different colors of lead in it--naturally it was a big, fat, round pencil! But the leads were so thick they were almost impossible to write with. I think they were meant more for drawing.

But the leads were so thick they were almost impossible to write with. I think they were meant more for drawing. Thanks for that information. I have here some "Col-erase" hexagonal wooden pencils in several colours, made by Sanford. One-day-old marks I made with them leave very distinct shadows when erased. I think they erase a bit more cleanly when erased right away, but maybe that's just superstition on my part. Anyway, those exist, but then they aren't a mechanical multi-pencil like the O.P. asked for. Just a similar experience with poor erasability. David |

There used to be Norma 4-color mechanical pencils about 40-50 years ago; we all had them in medical school to draw those complicated diagrams. Just found one at an antique sale - memories. LL |

Anybody who invents good erasable ink has solved this one, because multi-tip pens are common. But I've never seen erasable ink that really worked, and the semi-erasable stuff I've come across (I mean Paper-Mate "erasable" ballpoints) was always blue. (maybe they made other colours and I just never had one.) Note that there is fountain pen ink that will come out of paper with an ink remover chemical, but the remover basically ruins the paper, so that ordinary ink won't work on that spot anymore. Not a solution for real erasability. David |

I think rotring doesn't make this anymore but I have a tri-pencil of 0.35,
0.5 and 0.7. They now make quarto pens. In the past, I have seen besides rotring, Staedler and Faber-Castell use to make coloured leads. But they are mainly 0.5 I think. You could replace those multi coloured pens with a mechanical pencil. But you say it isn't sold separately. But I think if you could contact the distributor, they may be able to help. -- Best regards, Free Citizen http://www.freewebs.com/fpnet/ "Dave" wrote in message ... slag wrote: Does anyone make a multicolor mechanical pencil?
