Help Desk?

A reasonable number of people contact me trying to find out about the old mechanical pencil they used many moons ago back in school, etc. I'm afraid I'm generally not much help - so many zillions of pencils, so few of them ever made it my way, - particularly 10 to 20 years ago, i.e. pre-internet for me. Some folk email me direct and some leave their question in the guestbook - see the label on the sidebar. Anyway, as a typical example, heres part of the latest question on the Guestbook.

I wonder if you can help me find a mechanical pencil I used about 10 years ago...It was called "Spike," but I don't recall the manufacturer. It used a 1.0mm lead, which was my singularly favorite feature. I seem to recall a twist-out eraser, like a Staedtler. It couldn't have been very expensive, either, and I must have bought it at a discount store like Wal-Mart. Does this ring any bells?

So, maybe someone out there might know the answer and might want to help. And any of you who cruise by every now and then and are in a generous, helpful frame of mind, might like to keep an eye on the Guestbook questions and give us the benefit of your knowledge.
Thanks,
Dave.
