Favorite/least favorite locking mechanism?

When I grew up locks on folders were not even available as everything was a slipjoint. When locks came out it was and still is just a nice convenience. I find that when you use the knife properly it doesn't need a lock anyway but most of my EDC knives do have them because anymore that is about all that interests me as far as one hand opening and closing. Back before the Buck lock back folder was invented circa 1963-64 there were some large folding knives that had locking systems, but none had been successful. I believe this old Camillus one was one of those systems that fell by the way side after the debut of the Buck 110 lock back folder.

Personally I've always liked knives with a little pressure on the back spring. I used to collect weird lock mechanism knives. Still have a few but have traded off or sold many of them. One of my favorite old timers is a slip joint by Camillus called the "Cam-Lok". I carried this knife for years and it has field dressed many small game animals over the years along with many other tasks. Great high carbon steel too. This knife is such that you can use the lock if you want or if you don't need it you don't have to engage it. Basically this is a single blade slip joint folder about the same size as a Buck 110 or Schrade LB7 with a great half stop, super snap to the blade and a lock to boot. It is my all time fave lock mechanism. They should still make this lock IMO. To engage the lock you simply push the cream colored slide forward and it shoves a hefty piece of steel about 1/8" into a square slot in the tang locking it securely.

The Axis lock is the best locking system I have used. It is strong, secure and stable. It allows the knife to be opened or closed easily and with either hand.
 
Strangely, I think my favorite lock is the front lock (the lockback with the choil for the lever situated near the front of the knife, so you can use it easily single handed). This is because it is ambidextrous, easy to use and maintain and has proven to be reliable. Not to mention that symetry always had a certain appeal to me :)
The one I dislike more is the linerlock. Now don't get me wrong, I have a few linerlocks that perform great, but making a good linerlock is tricky. Make a steeper angle at the ramp and you'll get blade play, make the angle lower and the knife may disengage under pressure.
 
Favorite - AXIS lock. From my experience it feels the most secure and is the easiest and quicket to operate.

Least favorite - lock back, only because it's boring and slow to operate.
 
Lock-back (especially the Boyd dent) followed by the Axis lock.

I dislike liner locks.
 
Lockback,ala Buck 110,112.Was surprised when these tactical sidelocks started catching on.
 
My favorite is a DA auto. It can be opened with way and always available quickly. I have never experienced a lock failure of any kind. This may be because these are somewhat on the expensive (well made) side.

Least favorite I would say is the liner lock, always somewhat nervous jamming my thumb in a place where a very sharp blade can go. I like them when they are open, its the closing part I'm not real crazy about.
 
I generally slice with my knives, I haven't found a need to poke or stab with them. And I generally close them all two-handed for safety. So I feel comfortable with just about any locking mechanism. I guess my favorite would be a framelock. I've never purchased an axis-lock that just about everyone here seems to like. Some day...
 
Least favorite is the liner lock, which I find acceptable only for gents' folders. To me, it's proveably the most difficult lock to consistently make reliable, and even the best manufacturers and makers have a hard time getting it right often.

Favorite lock, my flip answer would be "a well-made version of anything but a liner lock". That's a little coy though ... really, right now my favorite is the axis, based on rock-solid reliability, a built-in closing bias (as opposed to ball detent), ambidextrous mechanics, and a long solid track record showing that the theoretical strengths of the axis are brought to life by Benchmade.

As others have pointed out, if you're only using your knife for very controlled slicing in non-binding materials (some people have mistakenly labelled this extremely narrow light usage as "proper usage"), it really doesn't matter what the lock is. A slip joint is fine. A liner lock is fine. But once you get to anything above very light use, you might get your blade stuck in a stem or in cardboard (yes, we've seen failures from both), and now you'll want your lock to hold. The manufacturers agree that this type of usage is reasonable and should not cause lock failure.

call me crazy but lock-back would be one of my lest favorite, liner being my least.

axis is on the top of the list for sure, and frame lock is on the top some were.
 
To be fair, I've tested my current linerlock against pretty extreme pressure (with safety precautions, of course--no fingers in the way) with the LAWKS off. I've really tried to break it, but much more and I'm going to have to stab it into something above me and do chin ups on it. It'll be hard to figure out a way to safely do that. I've seriously just bashed the near-tip of the blade, against the lock, against my desk (again, no fingers in the way) hard enough to see the indentations (through two napkins in my futile attempt to prevent scratches) notches into the red oak desk with the back of the blade, about 2mm deep. I'm now pretty confident that the lock could support my entire weight. I wish I had the money to just replace the knives that I might break. I'm sure I've got the tools to break any lock, but it would be difficult to measure the force of a forklift.

I'm really trying to sell myself on an axis lock (I already have several lockbacks) but benchmade's stuff, for the price, so far isn't hooking me.

Would you folks feel the same way if your linerlock knife came with a LAWKS?
 
The Axis lock is appealing but I'm waiting because in my own mind the jury is still out on how well that is going to perform over time. I had the opportunity to handle and take apart one of those Ritter Axis locks and there are two springs in there that control the movement of the lock. One was broke. I have been an auto fan for a good while now and have had springs break on those (good knives by Protech and Microtech too) and although they were covered the point is the springs broke. The Axis lock springs I saw were pretty small in diameter. Time will tell how well these hold up after a few years of use. If it looks like they are holding up I will end up with one also I'm sure.

Is anyone making an Axis type lock with BG42 blade steel?
 
Favorite? CRK Framelock, BM Axis, and all good lockbacks - in that order. I will also go out on a limb and say how much I like those very few well made liner locks that have come my way such as a BM690 and an Al Mar SERE 2K.

Least favorite? CRKT Snap Lock - if have you ever actually tried to use one you hopefully know what a disaster waiting to happen that thing is. Run away!

STR, I would argue that time has already told. How many years does the lock need to be out before you're convinced? We've had a pretty long time to watch the axis prove itself. Here are the things I'd argue that we pretty much know, after plenty of years of being in the market: 1. the lock is extremely reliable, 2. the springs rarely break, 3. and when a spring does break, the other spring still keeps the lock functional until you can replace the broken one.

Honest question: how many more years of seeing this over and over before you're convinced? The mini-Axis was introduced in '99, 6 years ago ... I think the 710, the first axis lock, was introduced '98 or so. Plenty of those first ones are around: my pre-production 710 prototype is still going strong! Not the oldest lock on the planet, obviously, but benchmade sold loads of these from the very first production run, so there's plenty of old ones around.

Good point and well taken Joe. I had it in my head that they first hit the market in mass in like mid 2001.

When the first coil type autos came out they appeared quite good also but then there were reports of failings and problems years later and I believe I recall manufacturers making bigger springs to replace older less hefty ones.

I believe that the Ken Onion 'assisted openers' by Kershaw were out for a few years also before many reports in a wave all at around the same time hit the forums of the torsion springs breaking in them. Springs bigger than the ones in the Axis locks too.

Earlier when I said I had the opportunity to handle one and repair it that is not the whole story. I had the opportunity to look at two actually at separate times. One came to me in pieces completely broke down. On the other some months later that had a broken spring, which I fixed, the lock was doing anything but working properly. In fact in engaged sometimes and at others it didn't go in far enough and needed help to fully engage.

Anyway, I saw the size of the springs in these knives and it just caused me to think that maybe they were 'fragile' for lack of a better word. The other thing I didn't really care for in the Ritter knives I examined is the unsecured stop pin for the blade. When I lossened the pivot pin on the Ritter I repaired that stop pin fell out before anything else was out.

I much prefer having stops that are secured with a small set screw or making a whole bar incorporating the spacer bar and stop pin in one piece on even my liner locks. This way it isn't prone to moving around or falling out if the pivot gets lose. I have not brought this up to cause a stir so please don't think that. It was just my honest observation after seeing the insides of the Ritter knives.

I have no doubt that Bench Made would cover it should something occur. Just my own opinion that in the world of knives even since the dates you gave it isn't really much time when a majority of those sold are most likely 'safe queens' anyway that are opened and closed only on an infrequent basis.

For those that carry them daily I have read both pros and cons. I am most likely to end up with one as I did like the look and feel of the knife for the most part. Perhaps a bit small for my hands but I'm sure there are other models now besides the ones I got in my hands.

To further try to explain my apprehension on the axis: I have no problem admitting that I am just a self taught back yard mechanic and yet I have already had two of the Ritters into my humble shop for repair. Both were modified slightly by the owners and the people that owned them thought they would not be covered under warranty by BM (rightfully so) so that is how they came to me for repairs. The first one is the one that led to the second one coming to me that I mentioned earlier with the broke spring. I published the repair of that first one on my home page and the second owner read about it and then contacted me about his.

To explain further. Bear with me I know it is getting into book level by now.

On the first one it had been modified by the owner trying to make the handle fit the hand better. In the process the springs popped out from under the handle and literally were not in proper working order at all. Granted this is not BM's fault nor a design flaw. I am not trying to say that it is.

After some discussion with the owner as to his options once I got the knife from overseas (Netherlands FWTW) to look it over he elected to save the S30V blade and pay a little for a new folder body from me rather than send it back to BM for a hefty replacement or repair fee.

I informed him of the fact that my work was all by hand, and that there was no way for me to remake the liners and handles keeping it an 'axis lock' because of the machining necessary. It was quite simply beyond my ability to remake it the way it was. I just don't have those kind of tools at my disposal.

With his consent I salvaged it best I could. He still carries it and uses it but it will never be as strong a lock as it once had even with a .063 frame lock thickness liner lock on it. It is strong though, just not as strong as the axis was by any stretch of the imagination.

I did manage to make it in such a way that he could go back to an original axis locking body should he not like what I did though. So far at this point that has not happened. His reference to me when he got it back was that it was a true 'tank of a knife'.

Perhaps seeing the two I handled fall apart at the slightest problem with the springs started me off on the wrong foot with them Joe. I concede that first impressions are pretty strong influences with me and that you do make a good case in their favor. At this writing though, that is the best I can give on it. I do appreciate where you are coming from though and thank you for giving me the update on the Axis locks true age.

Here is the repaired one I made the new body for.

I created just enough of a flat spot for the side lock to secure the blade but not enough to keep the old axis lock from working just fine (tested out to make sure) should the owner decide to go back to that at another time. In the mean time he could at least get some use out of that great blade while making up his mind.

Favorites: Axis lock, lockback
Least Favorite: Cheap liner locks! Buy $5 liner lock off of Ebay or something. Be sure to hold the wound above your heart to slow the bleeding...

I have no experience with compression locks so I can't judge.

Without wishing to sound argumentative, how does it fail? I have a A/F and it looks pretty much fail proof.

the gerber applegate folder isnt a rolling lock, FWIW. IIRC its a liner lock. not a rolling lock though. i am talking about REKAT folders.
