There you go being rational
True there can be doubt about one sided testing. Probably even more so when it comes to CS and their awesome marketing

For nothing other than curiosity sake, it would be interesting to see a neutral, well respected person do the same test.
Would it actually mean anything ? No, not really.
The spine whack test seemed really ridiculous. IMHO it seemed like the test was excessive. In the video it looked like a very hard hit.
Dare we say, Abuse lol...
I guess it makes a difference to those who continually ask, " Is this a good knife if SHTF "? If a person can't tell whether a knife is well made on their own, they aren't going to be able to survive in that kind of situation anyway. Besides, there isn't much need for a SHTF Bushcraft knife in the basement
I've never given lock systems much thought over the years, but I was taught by my Grandfather the proper way to use a knife when I was very little, and I carried slip joints growing up, and still do at times...
On the other hand, did this "test" possibly show that there is room for improvement in the lock area ? I don't know.
There is nothing wrong with improving things, IF they really need improving. CR has won enough awards for his knives, I think that speaks volumes, but nothing is perfect. On the other hand, I don't remember ever reading anyone saying the lock on their CR knife "failed" under normal use,
so apparently it's not a big issue...
