My PM 2 wishful thinking....

The compression is a safer more secure and stronger lock. Because the higher the force that is applied on an open knife's spine to force it closed results in an ever more secure lockup it is a very hard knife to force a failure. The lock does not fail iirc. The locking tab is compressed between the stop pin and the top of the blade tang. It really is an engineering marvel yet so simple a concept that you wonder why it hadn't been invented before. It is also fast, and when the tab is pressed all the over into its relief area, the blade is completely free which results in a smooth fast knife, vs. a liner or R.I.L. that has a detent ball dragging the tang of the knife the entire opening path.

The other thing is ergo's. I love the ergo's on back locks (esp. if you remove the clip) but do not like the back lock itself. The compression lock gives you that uninterrupted flow specifically where your index finger wraps around the underside of the handle. Some relief areas for liner locks can ruin how a knife feels in hand. Ball bearing locks, bolt-action locks, Hawk lock, and the axis lock all offer this safety (hands out of the way when closing) and ergonomic advantage.

wow i guess its quite clear which way people are leaning towards! guess i must be missing something when it comes to compression locks, I am however quite new to folders and very new to spyderco so happy to learn anything i can! What are the advantages that compression locks have over liner or framelocks? Is there less chance of the blade slipping or something?

Basically the compression lock is exponentially stronger that either a liner or frame lock. It is actually more similar to an axis lock or ball lock in the way the forces are distributed rather than a liner lock. The compression lock wedges a lock tab between the tang and a stop pin. For the lock to fail, the stop pin would have to rip right through the stainless liners and g10 scales or the lock bar would literally have to be crushed between the tang and stop pin, which would result in the lockup being compromised but not necessarily in the blade closing on your hand. Additionally, because the lock release is on the back of the knife, there is a much lower chance of cutting yourself while closing the knife. The compression lock may look like a reverse liner lock but the way it works is entirely different and far more advanced, not to mention stronger, more reliable, and safer. Add that to the fact that mixing a comp lock with a pivot bushing system like in the para2 lends itself to an extremely fun knife to play with.
 
The compression lock is quite different than the liner lock.



Linerlocks Vs. compression locks have resemblance but its application such differently. The load on a liner lock springs against blade., something like a long column. On a compression lock, the end of the locking piece is wedged between the blade and a stop pin. Load in this case being applied to a short, fat, much stronger column.
 
I really like the compression lock, so flicky and versatile in use, so one handed to open and close. Its an un-removable part of the Para2 to me.

BTW, sorry to go off topic but I just ordered a pair of Cuscadi wood scales for my Brown/S35VN Para2 and just had to tell someone :) ...cant wait to fit them...
 
It's good n bad for me, when I open the blade with the spydie hole slowly, my index finger lies on the back of the knife and gets pinched.
If I do the thumb flick, or middle finger flick I'm fine, or just hold the compression lock in and flick open and closed.

It's growing on me.
 
another nope. the compression lock is about half the reason i carry a pm on me. the other half everyone already knows who owns one.

wish more spyderco's used the compression lock. wish there was a military with this lock.
