Krazie,
Here's me breaking my vow of silence and being a pal again. J/K <img src="tongue.gif" width=15 height=15 align=middle>
The easy way to do things on your own is to do a search of the site, or any other knife site. Usually, Spyderco puts codes on their products dividing one of the same kind in plain and serrated. I did a quick search for "Cricket" in the Spyderco page, and came to the individual product page.
To find out the code for both kinds, I selected the plain edge first and put it in my shopping cart and this code came out: C29PBK. Then, to verify that it was the plain edge one (notice a P in the code), I went back and selected the Spyderedge one and came up with this code: C29SBK (notice the S in the code). I assume the BK is the colour code and it must mean black (????).
This is a long way to do it, but if I had no idea where to find it, I'd just start out like that with a general search and a little common sense.
Hope this helps!
