Late Full Lockup / Early Partial Lockup on PM2

Hey guys,

Wanted to post a few pictures and ask about something I noticed on my black on black PM2. The first picture shows the lockup position. From the research I've been doing, it seems like this is relatively late. It's either exactly in the middle at 50% or slightly past it. Most PM2 lockups I've seen have been closer to 30%. Does this decrease the lifetime of the lock? I do flick the knife open and closed quite a bit but I've only had it for about 2 weeks so if this is a problem then I should reevaluate the way I use the knife. Opinions welcome.

The second and third pictures are the early sticky or premature position. This doesn't happen when the knife is flicked open, or opened with any type of force. However, I noticed that if I open the knife very gently with 2 hands, it clicks into this early position where the lock bar has moved slightly but the stop pin has not fallen into the circular groove. The blade can still be shut although it requires more force than normal.

Anyone else seen this before? Anyway to fix it / is it normal?

Thanks in advance.
 
Your lock up is fine though I suggest if you want it to last as long as possible to stop flicking it for no reason. That goes for any lock type.
 
Your lock is where mine is. I wouldn't worry about it. If anything happens Spyderco will take care of it.
 
As for your early lock up problem, it's nothing to worry about. What you are hearing is the ball detent sliding off the blade tang and the lockbar hitting the tang. All of my liner and frame locks (as well as your compression lock) do this if you are slow and deliberate. Oh the fear we all feel when our brand new knife arrives. As a father of a 7 month old daughter, the only thing I have looked over harder than knives was my new girl. I kept asking nurses questions about if "this" was normal. My lack of experience and knowledge made me think everything was wrong when really it was a perfectly healthy little knife... I mean girl. :) Your knife is golden! Now, go cut things with it and enjoy.
 
My Satin/Camo Para 2s lockup is about 50% as well. I've been pretty worried about it, but I realized I should just enjoy the knife as it is. If it does reach 100% lockup, I'll send it to Spyderco or buy a new knife. Although I'm sure the knife will be fine for years to come.

I'm new to the forums, and I hope I could help!
 
You cannot judge a compression lock by the same standards you would judge a liner lock or a frame lock. It is a totally different concept and design, despite any perceived similarity you have. The other thing as rycen indicated is their consistent need to sit and flick a knife over and over and over again for no apparent reason. What you should do is try and find something a bit more useful to do with your hands, maybe buy yourself some Captains of Crush Grippers or something. That nervous fidgeting that so many people get is getting crazy, especially when they think their knives are potentially defective (as if the nervous tick has no effect on their perception.)

Thanks guys . Good to know the lock is working fine . Thanks for the advice but I definitely will continue to flick the knife when I feel the urge . Super fun. Besides, it's easily and cheaply replaceable.
 
Rotate your stop pin and report your results. If the stop pin is worn, it can cause lock up issues.
 
Can you rotate the stop pin without taking the knife apart ? Is it as simple as loosening the screws on either side and adjusting ?
 
Update:I rotated the stop pin by turning the screws on either side. Tried a variety of positions. The lock-up did not change and stayed exactly at 50% for all stop pin positions.
 
Mine is at like 75% and guarantee the end of the lock damn near hits the opposite side. Do I care? No. Does it work? Yes.
