I have a theory and have never seen it brought up, or explained. But if your liner lock, after a very long time looses it spring, and isn't at the original percentage, can't you just take it apart and slightly bend it in the direction you need it to go?

I posted it here because I KNOW someone here has a liner lock... :p

I think its not so much the spring, but the material wearing between the two contact points of the lock.
 
Yes, also if the material loses its spring it needs to be reheat treated completely. For the same reason the locks almost always work and have that constant pressure and angle, they can't be re-bent to shape.
 
Bob Terzuola's book "A Study of the Anatomy and Construction of the Liner-Locked Folder" is a very good reference if you are interested in liner locks. He explains things in detail with excellent photos.

Like the metal actually wearing down?

Yeah, think about it. When a liner lock engages, the tang and liner grind against each other at light speed (really fast) until friction causes the liner to stop. It's going to wear out faster than any other lock.
 
A Ti liner will actually compact at the contact area with the hardned blade tang. It will then sit there for a while untill actual wear starts to takes it further.
This will usually take long time to happen but wear will happen at a different rate on pretty much every knife.

There is a couple of options for breathing new life into a liner or frame lock like peaning the lock bar or using a slightly larger stop pin.
The spring of the lock bar rarely has much to do with it though.

I bought once Lone wolf T3 with really worn out lock...asked a local maker to fix it, and he did new stop pin, slightly larger in diameter. I think its best cure for liner lock.
