Does anybody have an explanation for why there have been so many PC's for sale recently, but hardly any of the older BM's? I have seen numerous 68's, 69's, other production models, and even some PC customs, but rarely come across a 30, 35, 44, 45, etc. How many knives were made in the production runs of various BM and PC bali's? People always talk about how much rarer the PC's are, which is why they go for so much more money, and therefore i'd think we'd see less of them, but to the contrary...Thanks for any info.
