This comment in another thread inspired me to start this thread.

How and or why do people dislike the compression lock? I really like both the shaman and the mini native and also the new flipper design...and the new wood hap40 delica and endura...i like them all I guess....

I have been mulling the compression lock of late.
First off I must say as a lock goes I find it about the most pleasant and civilized to use.

  • Civilized = little force required, no chance of getting cut if you don't hold the knife at the right angle.
  • Uncivilized (think Cold Steel Voyager back lock (((one of my favorite knives)))) = very hard to compress, at least on the smallest one, once the blade is released if done one handed and the blade is level or tip up some the blade swings down with enough force to cut the back of your finger. I know better and just did it yesterday.

and
Since I have been carrying my Ouroboros have been focusing in on the subtitles of the lock and the handles they are pared with. Since the Ouroboros I have become kind of obsessed with the compression lock.

what the heck is 'bagger babbling about this time ? ? ? ?

OK so anyway my only criticism has been the dip in one side of the handle, the thumb nail shaped cut out in the top of one of the scales. This is often where I want to grip the handle between my thumb and index finger and personally I want a broad flat surface right there. I have learned to adapt because I enjoy the knives and the lock so much.

That said I noted that the Ouroboros has a much smaller cut out than say the Para 2. It is still quite easy to get at the lock release so why not minimize the cut out in the Para 2 ? Gloves I suppose. One can use the Para 2 with gloves on.

That got me to thinking : what if one were to put a hunk of scale material on the release that fit closely into the cut out in the scale. One would have the full surface for the above mentioned grip and yet be able to press in to release the lock.

Down side, perhaps, more than likely, the release would get pressed when using the knife. A ?dangerous? risk Spyderco doesn't want to fool around with.

Then that lead me to recall my wonderful Gayle Bradley 1 and how it has a subtle cutout just inside the thick steel liner and not even in the scale and one can still release the liner lock.

How would this work on a compression lock ? I think it might be good for at least some of us. I don't need to flip for fun and mental health just for knife use. I pretty much would not need to release it with gloves on (couldn't with the GB1 either).

QUESTION : has anyone put scales on say a Para 2 that happened to not have the cut out for the compression lock and so had to get in there with your finger tip to release the lock ?

I'm thinking this would be perfectly doable since the lock takes very little force to release it.

I don't like the compression lock only on close. otherwise I don't care. tbo I don't want another compression lock knife. I have a pm2 and have no interest in getting another one. my problem is, I want a maxamet blade for edc (I have a maxamet mule which I cannot edc) and I have the choice between a pm2 or a para3 because I'm not interested in a LW frn model (the native 5 Lw and manix2 LW). so I may be forced to get another one.

in any case the lock is great other than on close for me personally, and I don't have any hate towards it. I'd just rather have any other lock type.

I wish the button for the lock was better. its so small. and often when I close it, it pops back up or I need to help it shut. its just not idea. I also don't like to go on the back of the spine to close it which I don't like either. I prefer liner or frame locks most.everything else while strong and good is just not as great for me in use.
 
I'm with Wolverine on this one. Even being a lefty, I find it super user friendly. I have 2 knives with the compression lock. A PM2 and a Yojimbo 2. Both are a joy to use. I am really looking forward to the Shaman.
 
It is a good lock, to be sure. However, I have never been pinched by a back lock. Just sayin'.
 
my experience is with SuperLeaf and PM2. I had no problem opening the knives or using the knives, but I had difficulty in disengaging the lock one handed. I prefer the CBBL on Manix and back locks.
 
The best iteration of the compression lock as far as use goes (for me) is on the Smock SK23. Kevin licensed the lock from Spyderco and the simple addition of the button is brilliant. One could argue that the way he implemented it loses some of the innate strength of the lock (hard to explain but the "compression" occurs in a way that could conceivably bend the lock bar), but I frikin love this knife. Obligatory pic.

Nice knife.
Yes that is sort of what I was talking about earlier.

No trouble with it releasing when you don't expect it to ?
Maybe when in a reverse grip ?
Never had an issue with the button accidentally compressed. Your comment got me curious though. For my XL glove sized hands, no issues with saber grip, pinch grip, hammer grip or any variation thereof. Reverse grip is fine edge out, but would pose a danger of accidental release if edge in. Given that this blade isn't really made for piercing/stabbing cutting, I can't imagine it would ever matter to me, but there you go. The only other grip I found that was potentially problematic was a draw cut grip. After trying out the grip last night, I would be afraid to use it in a draw cut given where the button is. Again, not likely to be a problem for me, but it is probably a more useful grip for my kinds of tasks than the reverse grip, edge in would ever be.
 
I have had a ton of compression lock knives pass through my hands over the years. For the most part, they are good to go, but some of them have some god awful stick to them that I could never get to go away.

This could change my life. tho his knives are generally thicker. the button is a great addition from the look of it. wont your hand grip the scales and release the button lock tho?

Doesn't even come close in most grips. I have no real concern about accidentally hitting it. Scales are quite thick though. It's not a lightweight.

maybe spyderco will put buttons on or make a production version of his stuff. I'm sick of buying customs.

I think he said that he was done with the SK23, so hopefully that means a production version could happen? Would be awesome.

Out of two para 2s and one Ouroboros (to be clear I like the Ouro and would buy it again) . . . talking just pivot performance now :
The Paras are like two gung-ho fire fighters and the Ouroboros is like a sleepy teenager being asked to get up early to go fishing.

The Ouro may catch the biggest fish . . . ha ha ha ha . . . but he sure won't be the first one in the boat.
The Paras just blow the Ouro away in free swing, consistency and general satisfaction in use. I just love using this lock and the Paras.

At the risk of repeating myself (I got up late and am still sleepy :)) . . . I wonder if the Ouro pivot has some G10 chips contaminating the pivot washers. Seems like I recall Nick's did.
 
I like the compression lock on my PM2. However, I don't like closing it with my index finger. I prefer to close it similar to how I close back locks with decent finger choils. I press the compression lock with my thumb, close the finger choil on my index finger, then move my fingers out of the way and make a second movement to close the blade.
 
Compression lock is one of my favorites, I have never had a problem with the cutout however, but I see how that would be annoying if you did.
The bushing pivot on the PM2 will make it swing free much better than other pivots, like the ouroboros without.

I want a maxamet blade for edc... I'm not interested in a LW frn model (the native 5 Lw and manix2 LW).
You could probably put a Native5 Maxamet blade in a N5 G10 lined frame.
 
bushing pivot on the PM2
I had to go watch a Nick YouTube to see what that is.
Thank you. That helps me understand.
Now I need to go look at the Nick Ouro disassembly to see the dif.
Realistically if I want to get all into it I could turn a new shouldered pivot for my Ouro . . .
. . . counterbore the seats in the knife ?
Anyway thanks.
 
"Not so likes" (?) = "dislikes".

No need to tip toe here, is there? It's not necessarily offensive to dislike things.

I never warmed up to the compression lock because I am used to an Axis lock which I find much more refined, and which doesn't tend to have the blade bounce-back that the compression lock has when quickly one-handed closing. I prefer Spyderco's liner lock (Millie so ideal).
