Oh good to know. I'm sure it has a lot to do with the knife itself but the Compression Lock on my Para Military 2 just works together perfectly with my hand. Very impressive. Thus far I would say that the Compression Lock is tied with the Ball Bearing Lock as my favorite locking mechanisms. And the Lock Back design on the Native5 is a close second (outstanding lock up on that thing !).wvguy8258 wrote:Work both slowly and look for the difference from a few angles. A liner lock blocks wedges a long piece of steel between the front of the blade tang and the attachment point for the lock. The compression lock wedges a short piece of steel between the rear tang and a stop pin. A compression lock works very similarly to an axis or ball bearing lock, only using a little piece of metal that looks like a liner lock instead of a bar or ball bearing with a spring. I see the only advantage to a liner lock being that it is cheaper to produce (it seems at least) and to add diversity to a collection. In every way I can think of I feel the compression lock is superior and perhaps the best all around lock for a folding knife.
Yes, exactly .Bolster wrote:Does the pliers analogy work, more or less?
Same here . I'm just going off the "self-destruct" quotes from those who have posted in the past. My wild west revolver imagery was likely more fantasy than realism.Bolster wrote:I would love to see a compression or CBBL lock tested to failure on a hydraulic machine. (As long as my four fingies were far away from the action.) The way you describe it sounds like it would be way cool to watch.
I don't see much similarity with a liner or frame lock, other than being a piece of metal that supplies its own spring force. I see it much closer to a bolt action or axis lock, in terms of the concept at work. It is a beautiful idea because it is so simple yet why it would be strong is obvious as well.Blerv wrote:The theory behind a Compression Lock is genius really. It's an evolution of the standard Michael Walker liner lock which doesn't devalue the original but has benefits it doesnt. Similar to what Chris Reeves did with his RIL.
The wedging of the lock between the stop pin and tang make it virtually impossible to close without destruction of the knife. It's the difference between throwing a large wrench between two gears rather than shoving a large block under the bottom of a door preventing it to open.
The main disadvantage is price and complexity to manufacture. It's self-close takes a bit of finesse which is something Spyderco has had to work on through the years...but they got it down to a science now .
Liner lock, RIL/frame lock, Caged Ball Bearing, Lockback, Compression...they are all amazing and very tough when done by Spyderco. Different flavors but all very tasty.
No, the function and theory is completely different. I have to think it took some inspiration from the limer lock based on compoments tho. Same as the modern wheel looks nothing like a rounded stone.wvguy8258 wrote:I don't see much similarity with a liner or frame lock, other than being a piece of metal that supplies its own spring force.

Odd, that's one of my objections to the compression lock. It's the only lock I've ever cut myself while closing. On a liner lock I turn the knife edge up, release the lock with my thumb, start the blade closed with my index finger, then shift my fingers and finish closing with my thumb. Have yet to figure a way to keep my fingers out of the blade path when closing a compression lock, regardless of which hand I use.Evil D wrote:I prefer not to have fingers in the path of a closing blade, thats my problem with liner locks. Compression locks eliminate the risk, and we all know there are times when multitasking its easy to lose focus and get cut so less risk is always good.

Deacon, that is exactly how I close mine too. And the Para2 lock, I usually close by using my index finger as a stop, which is what I am assuming you did when you cut yourself.Tdog wrote:On the Para 2 I simply face the knife down, use my index finger to press/pinch the compression lock an it virually closes itself (gravity). I'm having a hard time trying to figure our how you get your fingers in the way This is my favorite lock design. It's supposed to be on the YO2. Wish they'd use it on more models. I love this lock.
