These two folders arrived here this morning to me in the mail and I have never seen or heard of either one of them before now so I thought it was worth talking about them.
Both are listed as 5.11 knives and one (the better of the two by far) is a back lock design with a pretty great handle actually. I'm a bit confused by this one because I looked it up after recieving it and found its about an $80 knife listed as USA made 154CM steel but the blade on this one is stamped Taiwan. It does say 154CM on it also and has some rather nice grippy G10 scales covering .040 thickness stainless steel liners. In short I like this one. I could own it and be quite happy with it I think. The clips gotta go though!
The reason this one was mailed to me was because the owner feels the action is somewhat funky. I've examined the folder and what you are experiencing my friend when opening this one is this. Its kind of 'old school' here and a bit nostalgic really because for whatever reason, most likely safety, there is a distinct 'half stop' feature built into this lockback blade. I've seen this in lockbacks from the 60s and 70s too and have a few in my collection that are built this way also.
What is happening is that half way around the rotation the blade makes a very sudden flat stop like I've shown it here in the picture attached showing it half way open ( or half way closed depending on point of view) but the point is mostly this is seen in slip joints. This is something I've always liked personally and its generally just a feature that stops the blade in rotation before the back spring can slam it shut on fingers that are not safely out of the way just yet. If you note when using the folder its grabbing more on the close than it is on the open rotation. This is by design. Its not so much funky as it is rarely seen much these days.
Consider it an added feature that is there so you can both know where the blade is in the dark and also so you can get another second or three to clear the path of the blade before snapping it shut one handed. In interviewing police officers and others that work a lot in the outdoors where the have gloved hands this feature is something they look for and like to see because it is, according to them the difference between having to take off a glove to close the blade effectively or being able to manipulate it easier without the need to take the glove off and still close it without issue. Hope that makes sense.
Now as for the second one. Well its obviously a made in China folder. Its a liner lock but the liners are stainless steel and not titanium. The lock is about midway on the contact when opened. What you are experiencing here is two fold. One the detent ball is super super strong on this one. Man does it keep this blade shut! No worries of a gravity knife here at all folks! But, the contact is hitting on the upper of the lock instead of the lower where it should be. The reason you feel the blade give when you use it is because this lock has what we call 'rocking blade issues' due to the lock contacting the blade to secure it by contacting on the wrong part of the lock to the contact interface on the blade. The area of the lock contacting the blade is by the detent ball on this lock, which is way off! It needs to be lower toward the serrations for thumb grip which is the bottom of the lock that you put your thumb on to release the lock to close the blade. Once the lock contacts the blade here it would be hitting as it should be.
Then and only then will you have the proper contact where you have two points as far away from the centerline of the pivot as possible (the stop pin on one side, the lock contact on the other) to make the lock up solid.
I can fix this but I must advise that it will probably make the lock travel in even further than it is now.
