If you're looking for something that isn't spring loaded, but can open fast, I'd suggest looking at the crkt m16 line. The flippers make them open like an assisted, but there nothing to make them open on their own.
I cut the same spot with a benchmade auto 5-6 years ago.
It definitely sucked, but now it's just one more road on the map.
Don't push it, and feel better soon.
