Why would a frame lock be stronger than a liner lock??

Short answer, most aren't. They are arguably more reliable, since your grip tends to push the lock into further engagement, but most have a cut to reduce the spring tension to a managable level that leaves them no stronger than a good liner lock.

for the record, I have never tested a frame lock that held over 235 lbs (4" from the pivot) and these were top of the line heavy duty folders. this may sound good but it not. the knife was 8+ oz. I'd have to look at the video but as I recall the knife would have been unusable after 100-150 lbs.

This seems pretty conclusive to me.
 
I think most people just like them for ease of use and maintenance, they do well in those departments.
 
Why so many people are concerned with lock strength? I do not recall ever doing anything which required much lock strength. For all the practical purposes SAK is as good as any framelock folder for me.
I believe that lock longevity is much more important. I want lock perform consistently over as many years as possible. In this regard neither liner lock, no framelock are able to give me much confidence...

Do you even OWN any frame-locks?

Well if you were to ever stab something you would want lock strength, you know, so the blade doesn't close on your hands.
 
If I wanted to "stab something" it would only be with a fixed blade, never a folder of any kind.

Well, I've stabbed trees with my folder (for no good reason), and I still have all my fingers.
But for a NON-Prac Tac reason, try building this

With no lock. (disregard time stamp...I haven't been to the future yet:D)

lol Chris Reeve would like to have a word with you. A properly done framelock is in my humble opinion the most reliable and consistent lock there is while having excellent longevity. For example look at all the user Sebenzas from the 90s that still have perfect lockup to this day. Not to mention that it is by far the simplest locking mechanism so its easy to take care of and excels in the field. While I agree the framelock is nowhere near the strongest lock there is, it's still more than enough for even the hardest of KNIFE use. Also there's no way for the knife to fail on you if you have a proper grip on it while doing your edc tasks or slaying zombies :D.

Fine, you get a "well played" too. :p

Oh, and back to the topic, I'm a big fan of framelocks (and, for that matter, well-made liner locks). In fact, a good titanium framelock is easily my favorite type of lock.

Yes, their design, by nature, means that they won't be a very good choice if you want to baton with them or hang a bunch of weight from them -- an important EDC consideration to be sure (:p). The reason, of course, is that unlike some other types of lock their design doesn't allow transfer of downward (in the direction from spine to edge) forces to parts of the knife that are better able to bear them (e.g., the stop pin). But the simplicity and open design of a frame lock also means that they're much more reliable in the face of exposure to dirt, sand, and so forth (not to mention easier to clean). The strongest, most overbuilt backlock in the world isn't much use if it doesn't lock reliably in sandy or dusty conditions, and is difficult to clean enough to return to good working order.
 
If your edc is a folder, and for the vast majority of us it is, you may not have the luxury of going home to get your RC 5,7 or whatever before you stab whatever it is that needs stabbing. So, I think it's reasonable to expect that it, your edc, hold up to the stress.
Also, if I or anyone else want a folder that will stand up to a gorilla doing one arm pull ups off of it why shouldn't we have one.
Personally I love Kershaw knives. But I might love them a little more if they had axis locks. :)

Just wonder why?? because it´s thicker or... ????

Its not always stronger at all. The idea that a frame lock is stronger is just due to the thicker frame but the truth of the matter is that many liner locks are stronger and actually hold more weight before defeat or collapse due to the extreme lock cuts to make the beefy frame locks easier to manipulate. Frame locks carry thinner in the pocket, offer all the same advantages as a liner lock and some feel it offers more security and a better more reliable lock up that is still more than adequately strong for all applications whether heavy duty or not. Others feel a frame lock is no more secure at all than a liner lock while still others argue that its not more secure at all but simply a liability and easier to accidentally disengage the lock. The latter doesn't pan out in my opinion but thats my opinion. I tend to trust frame locks more but both types can and do fail at times or have been disappointing for some users. I tend to like smooth titanium bodied frame locks for one big reason. They are far easier on pockets sliding them in and out of your pocket so for me pocket rims last longer.

Typically when one of these type locks fails in use this is user error. Usually its from believing hype they read from questionable claims in advertising or from simply not really giving a new knife with an early lock up enough time to break in before diving right into a job that caused the blade to free up during use defeating the lock and cutting the individual. Of course its always the knife's fault or the maker's/manufacturers when this happens though. Never the user! ;)
