I don't know, and I don't really care that much, to be honest. I like having more control over my blade opening than flippers with bearings allow. My personal preference. However, if I was going to use bearings in a knife I designed I'd probably throw some kind of hardened steel washers between the soft titanium and the small, really hard ceramic or steel ball bearings with an even smaller surface contact. Or maybe harden the titanium or something. That only makes sense if you want your product to last with some real use. I'm not an engineer or scientist and I have no loyalty to a company that doesn't care about me for anything more than what I can pull out of my wallet so what I think doesn't matter to anyone.
If brandon whatever thinks it's retarded, it's probably because to HIM, it's retarded. Maybe I'm retarded but I agree with him. To YOU it's fine and you'd rather save on the final price and there's not much chance of wearing out freaking titanium so the practice is acceptable. That's also fine.
My wife doesn't work and is pretty lazy, but she's hot. I can't stand it (the lazy part, not the hot part). You, on the other hand, might be absolutely ok with it.
My dogs are ugly, they bark a lot, but they are freaking great at biting people who come into my yard unannounced. I love em. If you were my neighbor, you'd probably hate them, and probably me too for having them.
It's all about perspective and where you're standing at any given time.
