There's an objective standard. Everyone here has owned a linerlock, or multiples, or even many multiples, of linerlocks. Therefore, if we're to accept that they are weak, and that linerlocks have a real danger of opening in peoples' pockets as part of some design flaw* then doc there would have a point. Since there aren't any sticky threads at the top of this section with a title like "OMG BEWARE, LINERLOCKS ARE WEAK AND WILL OPEN IN YOUR POCKET!" along with like, thirty pages of comments of people recounting stories of such a thing happening, here on Bladeforums**, that tells me that no, linerlocks DON'T have some sort of flaw that causes linerlock equipped knives to open in someone's pocket on any objective, regular basis. This means that doc's attempt at an objective statement is flawed, and your own experience is also an outlier. Linerlocks are fine, given you aren't abusing the knife. That's another reason why a trillion people design knives with liner locks (besides it being free). Edit: Also, to make my own position clear (and to be on topic): I appreciate and prefer framelocks. Linerlocks though, are just fine with me, and of the like, seventy or eighty knives I've had, not a one has failed. Of course, I generally use tools to perform functions they were designed for. I use knives to cut things, that's about it. I've never had one fail, and I've not heard of any of my extensive group of knife-buds having a linerlock fail. *Hint: in other words, exactly the opposite of what's ACTUALLY happening. ** Only the biggest friggin' knife forum on the innarwebz.
