Has anybody out there actually experienced
a liner lock failure? The spine-whack test
is the standard test of a liner lock, but when cutting, we usually put pressure in the
opposite direction. I've yet to meet someone
who has had a quality liner lock close up on them.
 
Never on a quality liner but yes on some el' cheapos. The lock sometimes will not fully engage the liner and when you preform the test it will move to the side and allow the blade to close.

This is a post by Joe Talmadge on 17 Dec 1998 in a thread on the Blade Discussion Forum titled "Are the Rolling Lock and the Axis Lock still just lockbacks?" originator Win.

Joe wrote about someone who had a Microtech lock fail on him while cutting cardboard. The failure resulted in an injury requiring stitches.

I think you're right, most people just do some light cutting, and those people will never see a liner lock failure. However, I seem to have become the poster boy for liner lock failures, and so receive a lot of email about them. People seem to delight in telling me about their liner-lock-failure-injuries

Many injuries seem to happen strictly under harder use. For example, guys who test-thrust their knives into hard objects (the FMA community for example). Occasionally, it's not so hard use. Many examples are when a knife gets stuck or needs a little more pressure to get through, and the person either slightly torques the blade or begins white-knuckling it.

Anyway, I don't want to stop this thread, hopefully many other people would post. I just wanted to give a summary of what I've seen so far.

Slip joints and friction folders are just fine for the purposes of a lot of people. My issue with liner-locks is that they predominantly come on "tactical" folders, designed and marketed for hard use and defensive capability.

Just knowing that it very easily could happen, as demonstrated by testing, is enough for me. I don't need to crash a car to know that driving with bald tires is a bad idea.
