Ricardo,
In Buck's 2002 catalogue, there are only two knives which have blades of BG-42. They are the Four Generations Bowie knife, and the 191 Zipper, whcih is part of a four knife set called the Family Favorites. Every time we introduce a new Strider/Buck, the first 500 pieces are scheduled to be BG-42 as well.
I hope this helps,
