I hear a lot about liner locks that fail the spine whacking test. What I wonder is if everyone is in agreement about what constitutes a spine whacking test. Does everyone do it the same way? I`d like to hear from folks who regularly spine whack their knives. How do you do it? I`m curious how many different ways there are to whack a spine, and if the data we get is at all useful due to lack of controls in testing.
