Never an issue here either. I'm one of those guys who might just have a backup (or several) for his favorite Axis folder, so my hand is filled should the one with the broken spring(s) have to return to the Motherland for repair.
My question is, with all the pimp'n and modd'n of knives going on out there, how come no one has made any aftermarket Omega springs? Perhaps thicker with a little more tension? Perhaps titanium?
I give ti framelocks the nod for overall simplicity (and probably reliability also), especially with the steel lockbar inserts which to me are a great phase of evolution for the framelock in regard to long-term wear. But like Redmasta, the speed of opening and closing, and the manner of the locking mech wearing "in" a opposed to "out" keep me hooked on the Axis folders.
