I find Spydiewiki to always be a great source of info on such questions:
Looks like a run of 500 was done in '97-'98. Paul, it's called a "sprint" by them (which includes you, correct?
). I'd love to see an updated sprint in CF - Manbug, Ladybug and Jester!
Yes, I've been a contributor to Spydiewiki, and I think it's the best single reference source we have for historical Spyderco information. However, I don't always agree with everything written there. I'm not conceited enough to think I'm always right, so my disagreement doesn't necessarily mean they're wrong, just that what they're saying doesn't jibe with data I've encountered. In this case, Sal has mentioned that his Japanese makers require 1200 to 1500 piece orders, so a run of only 500 pieces seems odd to me. As for intro date, Spyderco's Across The Years
timeline puts it at 1999, but it does appear on '97 and '98 price lists, so those dates seem reasonable.
Given that they share the same handle, I'd bet that a "mixed run" of unlined CF Ladybugs and Jesters would sell quite well.
