They are talking about the BladeForums knife, which isn't necessarily a Buck knife. In fact, it is almost guaranteed not to be a Buck knife. BCCI does yearly and also special editions throughout the year. These will be Buck knives. The 35th anniversary knives that are being talked about are left-over ones from the 35th BCCI anniversary meeting at Buck. All these BCCI knives are either special ones that are commissioned to Buck or done by a private customizer. Buck on its own does monthly BOTM. They also do these "stealth" runs and web specials throughout the year. As an aside, you may also hear of SFOs. These were special runs commission by private companies (SMKW, Copper&Clad,DLT Trading, SKBlades,etc.) for special-edition Buck knives. Buck discontinued doing SFOs a few years ago (Buck please allow this again).
