(For the purposes of this discussion, I am going to use the term linerlock and framelock interchangebly since they operate on the same basic principle and for the purposes of this discussion, the distinction is fairly unimportant)

I like liner/frame locks, often though i am dissatisfied with the liner lock on a knife i'm examining, either the liner isnt thick enough, it goes too far to the right (which I HATE), or the angle between the liner and blade, the relative geometry, is awkward, and any number of these variables can cause me to view a particular liner lock as inferior. So, when i come across one that i think inspires confidence, im always pleased and i thought that it might be fun for us all to show a picture or 2 of the liner lock that for you, inspires the most confidence, the one that epitomizes rock solid, strength. I for one, would be interested in seeing your favorites.

For me, i look no farther than the Sebenza, and heres why. (Yes, i know its a framelock, but same basic principle). First, the Ti liner/frame lock is THICK!!! While its true that thickness alone does not make a liner/frame lock strong, since you can have incredible thickness and because of incorrect geometry have a fairly weak engagement, a very thick liner lock is nonetheless nice to see, and in my opinion, it IS one part of what makes a strong lock, and I have yet to see one thicker than on the large Sebenza. Second, the Sebenza liner/frame lock doesnt go too far to the right, i cant tell you how much i dislike a liner that strays too far to the right, and you just know that with a little use and wear, it'll go further and further to the right, screwing up proper geometry. I like the liner to stay towards the left side and thats exactly where the Sebenza's is. On the left side, but with plenty of engagement between the lock and blade. Next, the angle and relative geometry of the liner/frame lock and the blade's base just seem right to me, and you know that no force on earth short of a nuclear blast is going to flex that liner/frame lock. And finally, let's not forget the awesome, authoratative "thunk" sound when the Sebenza's liner/frame engages the blade and locks open, if you've never felt/heard it, you're missing out on one of the great knife related sounds. :) For all these reasons, the Sebenza satisfies the craving in me for a bulletproof, rock solid lock, to say it inspires confidence is an understatement.

I think one critical reason Sebenzas get so much hype and praise is this excellent, thick, rock solid lock, it inspires confidence and appeals to the many of us who appreciate over-engineering, and extra rugged functionality. I'm not saying the Sebenza can't be beat, but I think it's a tall order. :) Let's see whatcha got!

So, show me YOUR favorite liner locks! (Id be interested in seeing those by Carson, Obenauf, JW Smith, the Cutter/Brend and any others you have pictures of.)
 
...........on the Sebenza! It is the most solid of folders. With that said I will now go on to say that I also agree about liner locks either being too thin, coming over too far, or being angled in such a way as to cause them to close with slight pressure. This is why I have jumped on the Smith, Carson, Obenauf bandwagon. These guys don't scrimp on the liner thickness, their locks leave PLENTY of room for any wear that might occur, and they have the angles figured out to give you solid lockup. I wish I could post a picture of one of each with just the lockup area being shown because you would be hard pressed to tell whose is whose!

Are these the only guys to get it right? Certaintly not, but they are the ones that flip my burger!:eek: ;) :D

Good post Meg!
 
This one locks up rock solid. Can anyone guess what it is :)

The clip appears to be Darrel; the guard appears to be Maxx!

btw - I am loving my JW Smith Titanium Frame-Locking Recurve butt-kicking knife. Unreal lockup, buttery-smooth action, excellent fit and finish, unreal sharpening on the blade, impressive grinds.
 
So, lets get this straight. The design criteria for a good lock is:

- Thick
- Only locks partway in from the side of the blade.
- Makes a nice "thunk" when opened.

My Benchmade Spike (Phil Bogezwuski design) is 5 years old. It's one of the best modern stilletos or folding paring knives ever designed and made. It has never failed to lock tight, first time, every time. The lock has never failed. The knive has had a lot of use. However its lock is:

- Thin in width (1/32") and in tang contact (1/4").
- Originally locked in partway on the tang, but traveled 85 % of the way to the far side and has stayed there for the last 4 years. Don't think it will move any more.
- Makes a nice thunk, due to the open construction and aluminum handles.

So it only fits one of the two design criteria. By the way, the Spike is held together with only one screw and the pivot. It was $75 new.

Over engineering leads to additional cost and weight in almost any item. Over engineering is not elegant design. A 600lb lineman is over engineering, but unlike the 600 lb lineman, a 300lb lineman can at least run and score if the ball is dropped in front of him.

Criteria for a good lock:

- Strong enough for the intendeded use of the tool.
- Alows for relatively easy opening and closing.
- The lock is designed to handle changes in the components due to wear.

In some scenarios, a quiet lock is what is needed.
 
I don't have a pic but i recently purchased my first Microtech Manual Action.

I believe they call their "Liner Lock" the microbar. I had never seen one and was very impressed with it. It is not really a linerlock since the handle is all aluminum without any liners but the principle is the same. Rather then a bent piece of steel or Ti on the microtech there is a pivot and a spring to actuate the lock. VERY precise VERY SOLID

someone post a pic so i will be undestood

thanks
 
Geoff is right.

The Microtech Microbar is an impressive lock. If offers the same high level of engagement and thickness as the Sebenza (I've had two) and the CUDA Maxx (have one)with the added adavantage that the frame is not being stressed and it is much easier to disengage when you are ready to close the knife (my Sebenzas and the Maxx have all required two hands to close if the blade is snapped open).

The Microbar has the strength of a frame lock but allows the ergonomical scales of a liner lock. On the downside it is three pieces (pivot pin, spring, and lock bar)which make it less attractive than a frame lock for use as a one and only survival knife. It is an excellent lock system for an EDC self defense knife that can be inspected and maintained on a regular basis.
 
Yep, it is a Southwestern bell model :). Plus, you're all correct if you guessed a Darrel Ralph Maxx, although, it's a 4" blade Mini-Maxx. Can anyone guess the second one? It should prove to be a little harder. According to the maker, it is only 1 of 3 currently in existance.
 
Wow Neil...that's essentially a framelock! Can we see the Skirmish liners??

Here's another pic of the Mad Maxx lock...

BH can you tell me who makes the Southwestern Bell model?By the thumb studs I'm guessing Darrel Ralph or D.C. Munroe.If you can post a full picture of the folder that would be great.Also throw in some stats:) .Thanks

It is a Munroe . . . could it be a Direwolf?
 
RL,

Here is a pic of the Skirmish lock. Being a big knife, 11" OAL, 5" blade I made SURE to keep the lock as beefy as possible. There is over 5/8" of contact between the lock bar and the blade!! The liners on this liner lock version are .100 Ti.
