The picture of the para2 compression lock is great. You can look at it and understand why it WON'T close with out being released. Talk about creating trust. I got the same level of trust when I took my Manix2 apart and could see exactly how the CBBL keeps the knife from closing unless released. I'd love to have a few pictures of each lock like the one of the para2. The pictures in Edge-u-cation are ok when all you need is 2 dimensions. With a liner, frame and compression lock you need a picture to show depth also because that is the direction the lock bar moves. With David Lowry's picture shown by Evil we can see how it works.
I'd like to ask anyone who can to provide pictures of their knives when disassembled to illustrate the lock design. I'd be happy to try with my Manix2 and Gayle Bradley but my camera may not be good enough to show enough detail. The only other lock I have is the back lock and I haven't taken any of them apart. I don't want to take a knife apart just to take a picture of it. I plan on taking my GB and Manix2 apart in the future for maintenance so I can go ahead and do it now to get the pictures. You can easily see how a liner lock works just looking at it without taking the knife apart. Not so easy to see with the Manix2. If anyone else can get pictures like the one above we can put all of them in a thread. I know there is a great picture of the Chaparral disassembled showing the lock on the forum. That's a great one to show because of the stop pins on the tang and grooves in the liners for it. I think this is the first knife Spyderco used the design on. I'm not positive though. It is also on the Sage4. I don't see any need to disassemble a Sage4 if it is the same as the Chaparral, noy MY Sage4 anyway.
If people could take pictures when they have a knife apart I know I'd appreciate it and I think others would as well. I'm not suggesting anyone take a knife apart just to take a picture. Also, TAKING A KNIFE APART WILL VOID THE WARRANTY!
I'll put the Chaparral picture here since I already have it. You can see that in addition to the back lock stopping the blade the stop pin stops it as well. I think this is to reduce or eliminate vertical blade play from developing over time. I wish there was a picture of the blade open without the liner.
