No it didn't ! Where the video did you see that happen ?

You seeing a different video somehow or what ?

Is this the Twilight Zone ? šŸ¤Ŗ

Watch again sober please . start 7:30min. Manix 2 Salt is first one tested . Hits it three times . No unlock . Test done with a passing grade ! šŸ„³
 
(Asked AI if ball lock can withstand spin whacking . ) They are never wrong ! ;)

Yes, the Ball Bearing Lock is designed to withstand spine whacking, which is a test of a knife's locking mechanism by striking the spine of the blade against a hard surface. The design incorporates a ball bearing that engages with the blade tang, providing a secure lock that is resistant to accidental disengagement during such impacts. However, while the Ball Bearing Lock is robust, it's important to note that no locking mechanism is completely impervious to failure under extreme conditions, and proper care and maintenance of the knife are essential for optimal performance.

Woops, you're right - had to watch it all again. It was the second one. I was actually more interested in the contention that stronger locks are not any big deal as opposed to which knife or knives fail, and wrote up my thoughts while simultaneously preparing dinner. I have a couple of serrated Spydercos which I have sort of retired from daily carry in the role of SD/ERs in favor of a larger CS Kobun and a Pro Lite.

Anyway, the potentially stressful demands on knives chosen for certain activities, professions etc are not the same as minor day to day cutting tasks, so therefore lock strengths are an issue in my opinion. That is my take on the video and the general subject.

Agreed . :)
 
Are people really too stupid to understand that these tests are simply to show how strong a knifes lock is? Its obvious its not some "real world" test. Its so obvious it shouldnt need to be said that no one is actually going to be spine whacking their knife in real actual use, its just nice to know how well a lock holds up to abuse.

i remember Lynn at cold steel said and im paraphrasing.....what got him interested in strong folding knife locks was watching guides on african big game hunts use spine whacks to crack bones. also remember some fella talking bout watching someone pound in nails using the spine on a folder opened. so i guess some folks actually do spine whacking with folding knives.
 
I just put Lynn's comments to the test in my backyard on some mammoth bones I happened to have lying around. Naturally, I used my Cold Steel AD10 with Tri-Ad lock...

The results are incontrovertible...

It was a whole mammoth when I started. I need a beer.

I see some mammoth bone knife scale making in your future.....

People still do spine whack tests? What year is it? 2005?

I could whack the hell out of ANY folding knife hard enough and make it fail. ANY of them. Because they ā€œfoldā€.

Yes, even your precious Tri-ad cold steels, DocJD DocJD

I donā€™t know when people will learn folding knives are made because theyā€™re convenient to stick in your pocket, not to make em ā€œsuper dee duper strongā€.

Well said, these sorts of "tests" are so unscientific, not to mention anyone ones hands would suffer severe damage should they be holding a folding knife and exerting such forces LOL!

In my time as a senior mechanical tech and operator we employed lock out tag out where we de-energized the equipment disconnected power , locked the breaker in open position and cooled it down before working on it. This is Required by osha and company policy. Itā€™s smarter that way but much safer. Thatā€™s what Iā€™m getting at, work snarter not harder . Gloves and other safety gear help prevent injuries as well. Thereā€™s a reason bad things happen if youā€™re not working safe and smart.
