I'm getting very close to pulling the trigger on a Swift, but I have a question of the group here. I've heard a couple of anecdotal incidents of the lock-bar spring breaking on this knife. I know that Cold Steel puts a lot of time and energy into endurance testing their products. My inclination is to think that these couple of stories about the lock-bar spring are exceptions rather than the rule (lemons if you will), but I wanted to hear from some Swift owners here before I move forward. Have most of you here had good luck with this model?
