Balisongs And Caviar A Balisong Collector Special Exhibit ST3-X Pabu craftsmanship is everywhere on this exceptional knife. The unique latch is made of Damascus Steel. Even the ends of the handles have special file-work treatment. And notice how nicely the pearl inserts fit into their slots. Yes, craftsmanship abounds with adjustable pivot pins. Notice how closely the handles fit when the knife is latched open or closed. There's no gap between them. Yet the blade neither rubs the inside of the handles nor rattles loosely. Lock-up is tight open or closed. And, again, look at the colors in that pearl.
