LOL!!! "Trigger mechanism", "catch"? You mean the thumb studs, stop pin, and lock, that are on any manual folding knife anyway? You clearly have no idea how speed-safe works, and yet you are bashing it. I'll grant you that a safety is a completely unnecessary part that should not be on any folding knife, manual or otherwise. Luckily there are plenty of assisted or autos without them. You're fooling yourself if you think the spring, and machining the pocket for said spring cost the manufacturer more than a couple bucks per unit. And the R&D costs have LONG since been paid for. Whether or not the manufacturer chooses to charge extra is of course up to them. But seeing that there are plenty of US made Kershaw assisted openers for under $100, while the rest of the market approaches $200+ for their everyday manual items, tells me that the spring adds no appreciable cost.
