I've had a really bad run with omega springs; over half my Benchmades have experienced spring failure, usually both springs failing at some point. However, I have a theory that it is likely a *me* problem and not a *Benchmade* problem.
I have fairly caustic sweat. It was evident when I was making copper or brass/bronze jewellery. I'm fairly sure what was happening was I would have a knife in my pocket, I'd sweat while doing work (especially at my old warehouse job, oof), then use my knife throughout the day. I'm thinking that my sweat worked its way to the springs, in however miniscule amounts at a time, and caused incremental weakening of the springs at the greatest point of stress, the top of the springs arc. This wouldn't cause the springs to fail quickly, but usually within a year or two of carrying the knife regularly, one or both springs would fail.
At the same time, I am friends with several people whose EDC is an axis lock knife of some variety, and they've never experienced a spring failure, despite some being habitual flickers.
