This Curtiss custom F3 Large folder features a titanium bolsterlock handle with carbon fiber inlays and blue accented hardware. Its compound ground blade is made from damasteel with deep grooved jimping. Blade deployment is responsive, smooth, and results in solid lockup. The titanium handle has a notched backspacer and is outfitted with a recessed titanium pocket clip.
The F3 has the S.P.O.T. pivot with the IKBS bearing system. "S.P.O.T." stands for Stop Pin Over-Travel. The large diameter prevents over travel and up and down movement by improving the lock bar stabilization. Second, the stop pin locks into a pocket on the bottom of the pivot head and prevents the pivot from rotating.
