if you use your knife like a normal person a liner lock will be fine. if you do things like baton your folder through wood, try to stab it through metal, throw it, purposely try to make it fail or otherwise utterly abuse it yes it will fail. a kinfe is a tool and when used properly it will preform properly. I swear knives are the only tools that people use in completely asinine ways and then complain when it doesn't work. Knives are the only tools that people do everything they can to make them fail and them complain when they do.
Imagine of someone drove their car at redline in 1st gear until the engine shut off. you'd call them an idiot. it's the exact same thing as knife torture tests. it's like turning a blender on with steel bearings in it and letting it run until it shuts off. yeah cool you made it fail but let's be real with our tests.
