Axis Lock, Lock back, Liner lock... which is better?

i have read this thread with much intrest
real world- power plant electrician use
metal straps on metal conduit.. i would wedge the point in and hook the chamfer under one side and push down on the handle to cut the other side with the edge of the knife..
NOT an approved use i know but it worked...
i had the lock on a buck fail once doing this.. and seen many other lock backs fail as well as liner locks.. also the release on most can accdently be engaged partly doing this and the blade will close !
i still hook the back side of a blade under heavy duity tie tie's and push down on the back of the handle to cut through with out cutting what ever the tie tie is holding.

many say the spine wack is not a valid test ... as a shock test i dont know...
however i maintain a lock should be able to with stand closeing with a steady heavy pressuer to close the blade agenst the lock ...

sudden failure of a lock is never a good thing and i feel there should be a test to determand at what pressure a lock will fail to hold open the blade..
as a former hard use owner i am more concerned with the lock failing then being so easy to open..
this because that carrying a fixed blade was/is not an option at work or most places..
 
I am not sure exactly what the lock is called but, it is a type of liner lock. My Spyderco paramilitary has one and so far I like this type the best. I have cold steel with axis type lock, benchmade with axis lock and many liner locks and lock back knives. So far this one feels the best.

It is called the compression lock. It is a great lock design I agree.

Even though the axis lock can fail due to the omega springs, I have seen my uncle press a peace of wood behind the bar and it kept the blade open. Nice feature I believe to have for that accidental failure of the springs.

I like backlocks and axis and compression locks (in a manufacturer)......those are my first choices. then liner and framelocks (but with this said it depends greatly on the maker and qc etc. that will determine if it is reliable or not for me)
 
back in the 70's & 80's when I carried lockbacks, I had them fail due to lint/etc getting in the way regular enough to where I would regularly take a toothpick & clean the slot out. Then I discovered liner-locks, they are either right or they're not. As a previous poster mentioned, I guess one of the hardest jobs I put on mine is thick wire ties, pushing the point in like a wedge & then pushing the blade thru, I always push away from myself, but often you have (or I do) wrap your hand all the way around the handle & rear up on it pretty good
