The black one is the one I used the most of the 3 (kinda obvious) That knife has been through hell and back and confiscated I don't know how many times. Most controversial confiscation was the Pentagon. It may sound obvious why it was taken but, I was able to get in with my M9 and 3 mags on my duty belt (USAF SF/SP days). The 2 larger knives both purchased same time but the stainless one went missing for about 8 years. The smaller one of the 3 was got last year or so. SOG is only 2 to 3 years old in comparison from clothing sales as a early fathers day gift.
