What the heck are you guys doing that would make a liner lock fail? When you cut something do you also use a hammer blow? Do you stick your knife into something and twist it with a vise-grip? In normal use it is hard to get a liner to fail! I have used knives with liner locks (AFCK-Mini AFCK-spyderco's-Emersons) on a daily basis and never EVER had a failure.So why is everyone so hung up on how far a knife has to be abused in order to break it.
