Hey everyone, I've got a quick question about the workings of the compression lock before I murder my meager knife savings and pick up a Para 2:D I'm curious about how the compression lock works; I've seen photos, read the patent, and looked at other threads, but the bit of info I couldn't find is this: When the knife locks open, the lock tab wedges between the blade tang (which is ramped, I'm assuming, like a liner lock) and...what? If it's the stop pin, it seems like the lock tab would have to either a) be in constant contact with the stop pin or b) the stop pin must be ramped like the tang, or c) the tab doesn't normally contact anything, relying on the stiffness of the liner, but if forced, it would wedge against the stop pin. This question is just to satisfy my own curiosity, I'll probably pick one up anyway.

Oh, and how thick is the tip? Endura FFG style, Griptilian style, Leek style? Just curious, I don't pry with my knives, and I know the tip has a proven track record.
 
The tip is pretty dang pointy not too thin but I wouldn`t stab a paint can too many times with it. I will leave the comp. lock question to someone more informed.

See bold blue above.
 
So is the stop pin ramped, or is the liner in constant contact with the stop pin, or does the ramp of the blade tang push the liner into the stop pin?
 
Good question. I played with it. I can wiggle the blade up & down a bit as I slowly let the liner engage (moving it with my finger). The play lessens as the liner moves out & stops completely near the center of the tang. Yes, the tang is ramped. Can't feel the liner rubbing the stop pin at all on the way out.

There may be a very slight twist in the liner to help it miss the stop pin until it reaches the center. Or even a very slight ramping of the stop pin. I can't see either, though. It's not just engaging the tang at full lock up. I tried hard to wiggle it up & down without success. Very tight, solid lock up.

Definitely pick one up if you're even slightly interested. It lives up to all the hype you read here. Not only does it have no obvious weakness, but in every area I can think of to judge it, it's conspicuously strong. Looks, ergos, blade geometry, smoothness, steel, heat treat, lock, fit & finish, weight, clip, ect. All strengths.

Yeah I didn't pay attention to it until recently, but it seems to combine everything I love about the manix 2 and delica into one knife. Similar size and quality feel as the manix, with lots of strength, but as easy to carry as the delica, with great steel to boot. Damn I hate/love this hobby.

Thanks for the help everyone.
 
It looks to me like the stop pin is anchored in the nested skeletonized steel liners that run the full length of the handle. It doesn't move. Very strong design.
 

Got this off Spyderco's site. Believe me you can't go wrong with the Para2, I got one myself and its awesome!
