Spyderco Compression Vs Ball bearing Vs BM Axis?

[chiral.grolim]

...the probability of a Compression lock actually breaking (stop pin / liner / lock-bar) is far less likely than a broken Omega Spring.

...I've never experienced a lock-bar traveling more than 50% on a compression lock, but could I not also rotate the stop-pin on a compression-lock model to basically move the wear outside of contact on either the lock-bar or the blade-tang in order to achieve good lock-up again (I've had my Paras apart more than a few times, but I can't honestly remember if the stop-pin is keyed on one-side)?

I direct you to my earlier reply on this, post #31 above. A broken omega-spring (or even two) does not compromise the axis-lock, it just changes its operation a little, and wear on the stop-pin is of less concern (less likely) than wear on the compression-lock liner which is softer, weaker, and cannot be rotated, and also on the blade-tang itself which again cannot be rotated. Also keep in mind, as I stated above, that the axis-lock employs 3 pins to distribute force into the bolsters vs. 2 on the Spyderco models.

O no...what to do if I am far from home and the omega springs break?

If there is a catastrophic failure in the BBL the same can be done, just use a bigger piece of wood. That is what I like about both of these locks in my experience.

Can all three be operated with gloves?

In my experience yes. All three are well engineered locks. What do I prefer....well, the overall models influence that decision more then the lock itself and that goes with my mood or what I feel like carrying that day. So cant really answer the question :foot:

Compression lock, unequivocally. And not just because it's a compression lock per se, but because mine has a PM2 wrapped around it. Neither of the two axis-locked BM I've got can be closed with one hand comfortably, whereas the PM2 is faster to open and close both than any of my assisted Kershaws. It flies out open and locks like a vault and then freely swings back to close with an ease and grace of a high-quality balisong. Yes, assisted Kershaws and Benchmades pop out open faster, but closing them is a different matter altogether.

1. compression (again, at least in PM2 package - nothing compares to it, not even close)
2. frame with Hinderer stop - not in this group, but the second place nevertheless
3. axis sharing the spot with BBL - those small parts like springs, etc. just don't sit well in a hard working tool.

this is a nice trick, I like it! so simple, like the lock

I hope the spring on my 710 will always stay strong but if they don't, i now have an alternative until it get fixed

neat trick. i dunno what i would do if the lock on my delica or sebenza would fail.

I am curious as to what type of use is causing all this heavy deformation and wear on these 3 kinds of locks? All of them are designed to compensate for wear of the locking element via an inclined plane, although the travel available on the compression lock is shorter than on the others.

I prefer the compression lock because of its brilliant simplicity. There is less to go wrong, fewer parts to fail or get lost. The axis is second, also brilliant but more complicated. For some reason the CBBL just leaves me cold.

It is worth noting that all three of these locks function on the same basic principle of compression, as does the Demko tri-ad design.

Some people do dumb things to their knives that cause the locks to deform. Look at the requests in the general forums for a folder that can take a pounding with a sledge hammer, be light, have great edge retention, ease of maintenance, ease of opening and closing, lowrider 4 way clip, perfect fit and finish for under $100 that someone can beat on and never have any issue with.

Agreed, the compression lock definitely IS designed to account for wear. The lock face on the blade tang is ramped much like a liner or frame lock. If the lock bar deforms (is compressed) slightly it simply settles further into the lock face. Under normal circumstances I don't see vertical play resulting from lock wear but more so from possible deformation of the stop pin due to repeated aggressive flicking.

Truthfully though, between the axis and compression locks, I don't pick favorites. I do think a pm2 with an axis lock would be pretty slick though, but I suppose a 710 with a comp lock would be really cool as well. Maybe someday...

I like the compression better. Mainly because if even one of the springs in the axis lock break, the whole lock fails.

This is completly untrue! The lock functions even with both springs broken. All that broken omega springs do is change the smoothness of deployment. Hell, when one broke on my mini ritter, it was actually easier to open and close than before. Benchmade sent me some new Omega Springs, and two minutes later it was back to new. They even sent me a new pocket clip and set of screws.

Compression lock may be strong but I thing the Balisongs/Butterfly format knives are stronger ! Although they aren't really locking blades , but if you hold the handles, the blade is never going to fold on you !
