Hi fellow forum members and users.

What lock will WEAR fastest of these:

1- liner lock
2- Lock back
3- Frame lock
4- Axis lock

I am not asking which lock is stronger. I am talking about wear.
Thanks.
 
axis lock. my 530's lock broke in 14 months. the only problem that i see with the axis lock is that it relies on very thin omega springs which are subject to wearing out
 
On the other hand I've had a 940 that has been going for years of edc with no ill effects to the omega springs.The axis lock is built to wear in over time.Any wear that might occur will simply result in the lock engaging the tang more fully.
 
gundude, you are describing a failure, not a wear out. That is totally different.

I guess in all cases, maybe except the lock back, you see a "wear in". "Wear out" is something more theoretic.

For my part: I am using axis locks over five years and i don´t notice any kind of wear.

I have an older liner lock whose liner has traveld to the mid of the tang. That is more wear in than wear out.

I have my oldest one, a lock back, which has blade play in all directions. But i count this on the fact, that the folder is pined together not screwed.

So all in all: The liner lock will show the most "wear" (liner travels over) but hardly to the point of going over to the other side.

Everthing else is a question of product quality.
 
I've had 2 EDC lockbacks wear out - i.e. got to the point where the lock didn't hold well enough for me to consider it safe for me to use.
I've not owned an axis lock, and have not carried a frame or liner long enough to answer on them -- but the 2 that I consider "failed" were by major manufacturers and were carried/used daily for more than 5 years each, so I do not consider them to be "bad" locks - or knives.
 
Within liner lock models there are significant difference in designs/materials etc. Same applies to the other lock types.

This question simply cannot be answered. Need to limit the possibilities. State specific models so a basis can be made.

Example liner locks generally wear faster than frame locks. With exception when the blade tang cutoff (lock interface) for the liner lock is curved instead of flat. Example is Spydie Military, it has significantly longer wear life compared to all my framelocks.

Though some locks travel or develop bladeplay, for some it does not mean it cannot function safely. For my framelocks it does not make a difference it the lock travels all the way since the framelock thickness is thicker than the gap of blade to opposite scale.

I won't ramble on. I find I become not too coherant as I ramble on.

Hope this hepls.
 
I've never had a lock of any kind "wear out". Except maybe my old Benchmade Stryker- in which case, the titanium liner lock sort of lost its spring after a few years of carry and hard use. It still works, but the spring pressure is very light.
 
I think in theory it is gonna be a liner lock that "wear out" the fastest, due the liner migrating across the tang, but i think thats in theory, you have to account for if the knife has been well taken care of or not and the materials used, as well as the overall quality of the knife and the linerlock, IMO

Exactly. There are overbuilt, and wimpy versions of liner/frame/back locks, different models use different angles on the wear surfaces, plus there can be large variations based on material itself. A good hardened steel liner is going to wear a lot longer than a ti one, for instance. An Axis lock shouldn't wear too much, but those springs ARE going to break, eventually.
What lock will wear fastest? That depends.

well it did not simply break. i felt the lockup degrade and then it finally went
 
I think the axis lock will wear the slowest. I've heard of omega springs breaking, but that seems to happen randomly rather than over time. To me, blade play develops when wear occurs, and I haven't heard of that happening on an axis lock knife. I think second would be a frame lock with a carbide coating on the lockbar interface. I've heard of people with XM-18s that have flicked them often for several years, with no change in lock up percentage.
 
What do you think about this liner lock?
Being thicker, does it mean longer life?

That's about as solid a liner as you are going to get. You'll probably wear the blade down before that that will wear down.

FWIW, my BM 940 is going on its 10th year, and must have had a few hundred-K of "flipping" at this point, still no problems.
 
I have a BM 730s and have used it for 3 plus years and never had a problem. I had a BM 910HSSR and beat the crap out of it for 3 years and never had play or lock wear beyond a MM or so.
 
In general I would say the liner lock.
It really depends on the manufacturer though, sometimes individual knife models are drastically different. The liner lock on my Kershaw JYDII will probably last just as long as the Axis lock on my Benchmade 14255. Not so for my Kershaw Blur, however, as it wore in halfway in its first week of use.
Then the lock on my Buck Bravo was shot right from the start (and the handle design was terrible. After a bit of a makeover however, I now like it a lot).
The troubling thing is that the price of the knife has little to do with the quality of the lock. There are some $50 knives that are as strong as anything out there, then you could get a $500 custom/high end production knife with sloppy design.

+1 ....... :thumbup:

Maybe I have just been lucky, but I have never had an Omega spring break..... yet anyway. ;)

I am confused........ :confused:

Are you saying the spring / springs got weak and then finally broke???
Both springs or just one of them?

Or, are you saying the AXIS bar broke???

Not possible. By design.

You wouldn't feel the lock up degrade.The springs would just brake,and that would be it.

I don't know... IF the springs somehow weakened before they broke..... would you maybe not feel a difference????? However, that being said..... I do not see how this could even happen unless the springs had been removed and tampered with.

Either way, I have never had any problems with any of my AXIS knives.

Have you tried taking it apart and bending the liner more to give it more pressure?
