From what I can gather I think it was the later models in either early or late 03 just before they were going to discontinue them. I have a friend who has one of the black coated, PE, G-10 models in VG-10 but truthfully it is the only one I have ever seen. I would say that they are fairly rare. With the popularity the C-46 is now enjoying sinced it's been DCed I would say the VG-10 model would certainly have collector's appeal in probably the no so distant future. I would venture to say that percentage-wise there are probably not very many of them out there compared to the ATS-55 model.
Either blade steel> they are still a super knife. I never really was all that "gung ho" about tantos but Bob Lum's tantos are a completely different animal all together. Great knife. But then again what would you expect from Spyderco :thumbup:
