There were many reasons the new BKT knives are far superior to the Blackjack made models.
1)Superior scale material-GV6H is much, much stronger than the old "esta-loc" scales that Blackjack used.
2)Superior steel selection/heat treat. Blackjack made BKT's out of 440-a, 440-c, and 1095. 0-170-6 is a superior performer in a big cutting tool.
3)Better fit/finish-the BKT product now is much better finished than the "old" BKT. Grind lines are straight and visible. Handle scales fit better, edge sharpness and thickness is more consistent.
4)Better sheaths. MUCH better sheaths. the old BJK sheaths stink (That is being kind) the new kydex or propex sheaths are very, very good.
Better prices too. Camillus kept the prices the same on many models and has copme out with several CHEAPER models (BK-7, BK-9).
Better all the way around!~
