There should be two springs. Did both springs break? I'd discuss the shipping issue with Benchmade. Since they are the source of the springs, you'd need to go through them to fix it yourself as I don't know where you can otherwise get them. I've never broken an axis lock spring, but IIRC Benchmade is not big on customers dismantling their knives. Good luck, keep us informed.
