Help me understand : Why does a pure slicer needs a strong lock ?

Chapp said:
The PM2 handle is built like a tank, but the blade is quite delicate (to not say fragile and not hurt some defensive persons). Why does a PM2 features a bulletproof compression lock, while the bigger (intended for bigger task) Military features a linerlock for example ? A linerlock isn't as sturdy as a compression lock usually. Maybe that's uninteresting or strange to you, but to me it's not.

Spyderco hasn't released the lb test numbers for either models so you can only guess if the comp lock is stronger or whether one breaks sooner under load. They do have a lab and test that but it's held as proprietary information best I can recall. My guess is both would have broken blades before the lock would break under most situations where force can be applied and measured. I'd say don't underestimate the Millie. It's one tough sucker known for it's long life when used as a knife. That is the same as the comp lock models.

Its history doesn't really solve the paradox of the choice of lock for the PM2 and the Military.

I'd like to know what paradox you are referring to.

The big brother, intended for heavier use, having the weaker lock of the two (Military vs PM2). That's a paradox.

We don't need any Spyderco lb test. Linerlock, albeit perfectly fine, are among the weakest lock by design. Every test under the sun reached that conclusion and the Military isn't some kind of black magic.

There’s a thread on here that Sal responded to, stating that the design for a compression locked Military is done and the model is still in the works.
 
Because I don't want that super-slicey blade closing on me.

The compression lock on the PM2 is perfect. Easy to use 1 handed, lets blade open fast, secure. Who cares if it's too strong when it does what I want so well?
 
Perhaps the OP would appreciate this Manly Comrade? The blade is a hair longer than the PM2, it's nice and slicey, and no pesky lock of any description. I know that LEGION 12 LEGION 12 admires my Manly Comrade. Here it is by the smaller Wasp.

I really don't think that there is a paradox here. The military was made before the PM2. If I remember correctly, this was before the compression lock was even invented. The smaller PM2 was made for ease of carry, operation, and a general update to the line. In order to "update" the Military, that would be a lot of sunk costs in new molds and manufacturing of a model that was currently selling just fine. Its just progress. For 99.99% of use cases, a liner lock is just fine especially for a slicy blade. The compression lock is just better. It is stronger if you need it and it is a safer lock in that you dont have to have your fingers in the blade path when you go to close it. Like others have said, I know there was speculation at some point that the military would eventually have a compression lock update as well and that could very well still be in the works.

So to the OPs point: yes there is such a thing as good enough but knives and carrying of such really isnt about "good enough" mentality otherwise there would be no such thing as CRK. A liner lock is good enough for 99% of cutting and a Civivi or CRKT is probably good enough for 99% of carry duty. Sometimes we want more capability out of our gear and better, stronger, and more convienient locks are part of that.

You may think you know which one is stronger but that does not make it so. I'll wait and see tests before I make up my mind. Now practically speaking I'll say both are stronger than they have to be and both will have a very long lifetime if used as designed and somewhat cared for. Neither needs much. Most likely the blade will break before the lock.

I have many models of each and like them equally though I do prefer a lockback design over either.
