well i hear all this new terminology here so this has gotten me confused, which is very easy to do, whats the differance between joint lock, frame lock, slip lock, i dont know maybe there are more or maybe i made some up....i just know what mine look like and how they work not this 0.75 cent words they are hard and confusing....thanks for helping the weak minded...
 
A frame lock is where part of the knife's handles locks the blade. Most obvious example is the Chris Reeve Sebenza (he invented the frame lock). A liner lock is similar, except that instead of the frame/handle, it's a liner within the handle (or scales) that locks in place. Usually thinner than a frame lock. Example: Spyderco Military. Invented by Michael Walker.

A slip joint isn't really a lock although it does keep the blade open. Most obvious example would be a Swiss Army knife or a Shrade Old Timer. The backspring presses against the tang of the blade and holds it open or closed. It's not a lock, since you can slip the blade open or closed, hence the name.

A good glossary on knife terms can be found here.
 
Ill take your word on who "invented" the frame lock.

But the liner lock waaaaaaaaaay predates Spyderco. The Camillus electricians' knife has a liner lock on the screwdriver blade and it dates to WWII or earlier. The Camillus Cub Scout knife was the first liner lock I ever saw, in about 1974 (I was 8). I believe the liner lock predates Mr. Walker entirely, as well.

The lockback, the other major lock form, uses a recess on the tang of the blade near the pivot. A correspondingly sized portion of the spring pops into the recess upon opening. The spring must be pushed (in some ancient cases pulled with a ring) to disengage the spring from the recess.
 
I know it's just symantecs but a slip joint (AKA Slip lock) is technically a lock because it stops the blade from closing on its own.

A friction folder is what I consider lockless because it has no mechanical means of stopping the blade from closing without the user grabbing the handle.

Nate, don't mean to confuse you more, sorry. Here's a friction folder..

Now I know we're clearly in the computer age. Semantics becomes a brand name of computer software. I'm not criticizing. I'm just getting a kick out of it. Take care.

You mean we weren’t talking about virus protection?

He didn't say that _Spyderco_ invented the liner lock.

Walker lock= Liner lock. The Spyderco Military is just an example of such.

Though I can see where it may have sounded like that when read ;)
 
the reason that walker is synonymous with the liner is a misconception. He will freely admit he didn't invent the lock. he did invent the ball bearing detent that holds the blade closed.
 
I guess the "Walker" liner lock I see attributed to him (Spyderco, AG Russell) is the updated, modified system we see in knives today.
