Yeah, I gather some people have lives too complex to spend coolhunting the Internet. Some of the rest read NOTCOT, which is a lovely site but has TOO MUCH. I may not have a life but I like to eat at least once a day, maybe wash, you know? There are many other fine blogs and sites conglmerating nifty stuff. Thinkgeek will sell them to you for a mostly reasonable price. But once in a while I find myself the envy of my friends and then I shall pass the word on.
Such a product is the Stainless Steel Sharpie (Sharpie.com is down, or I would have linked there).
I found out they existed because way-cool science fiction writer William Gibson (who ought to be made out of bulletproof nylon and brushed titanium, but who seems to be rather a sweet guy) had a new book come out and one of his fans gave him a stainless steel Sharpie. He tweeted about it. I figured that if he liked his, it was cool enough for Dick the archaeologist.
I hope they will make it in 'ultra fine', which is what most people would call 'normal.' SCRAP uses the ultra-fine on artifact bag tags and the allegedly 'fine' (which is kind of bold) for marking other stuff. For the moment, Dick's image as a frighteningly au courant executive is secure.
