But testing doesn't tell you how good it is. If you look at how climbing gear gets tested you see when and how it breaks, not that you can eventually beat it into submission. The order of testing methods, sample size and a dozen other variables mean that most knife torture tests are largely pointless. Unless they can provide a direct comparison to something else, or to a specific failure mode, they mean almost nothing. Sure a single direction "against the lock" pull test is repeatable and may have value. But a lock holding or not while being beaten on from different directions doesn't tell me if the lock is peening, bending and recovering, or working looser/tighter. It doesn't tell me if the pivot threads are failing, washers are galling or stress zones are building in any particular location. Partly that is a cost thing, no one that I know of can get 100 knives to do ten cycles of ten tests per model.
And if you've ever worked with an apprentice, you will know that some people just naturally find the way to break things, even things that shouldn't be breakable. Does that mean they are bad items? Maybe, maybe not. Knife testing relies heavily on the tester, and it's so easy to manipulate,
Last, the fundamental assertion that your version of an EDC knife is the only valid reason for carry is a logical fallacy. For those of us who cannot carry a knife for self-defense purposes by law, and who carry it for other utility purposes, or for sporting/recreation, is that somehow less valid? Is my carry of an EDC which is good for food prep less valid since I cannot rely on restaurants and so may have to prepare a meal with little notice, less valid because I'm going to pick something good for food, and not getting into a fight? Or is my work EDC which is all about solving odd problems less valid? Because I cook and fix things far more often than I self-extract from vehicle crashes and ambushes. And honestly where I live, if I had to present a judge with a piece of pocket jewelry to make my case, I'd probably be in a better situation than if I had a vic paring knife in a cardboard sheath in my pants.
