CRKT's LAWKS

It's this little switch that you push with your thumb that blocks the liner from closing.
 
its a flat disk mounted between the blade and the liner, which when pushed blocks the liner lock from going off the blade tang (which would, of course allow it to close).
 
It works this way:

There is the thin steel disc between blade tang and frame what is rotating around the pivot pin, exactly like the blade but separately. On the upper (spine) side it has the tiny level positioned in thumb placement area what allows to rotate this disk forwards and backwards. At the opposite (edge) side there is the small shoulder bent perpendicularly to disc plane.

When you will grab the handle in working position it is very natural movement to push this level forwards, if properly executed it literally asks for this. Suitably the down side of the disk will go backwards and put locking shoulder between the frame and liner preventing this last from unintended disengagement.

When you want to close the knife just pull the level backwards with your thumb. This will move shoulder forwards releasing the liner. Now you can disengage it like each liner lock. This sounds quite accomplished when described, however all motions are very natural and practically do not obstruct knife operation anyway.

The pictured knife is CRKT – Kit Carson M-18, very interesting knife by the way, true tactical folder.

HTML code is off, so I have edited the spells to make images visible.
 
I'm pretty much ambivalent about the LAWKS. I can imagine that it would be pretty handy to engage for longer knife chores, but in reality I don't find myself ever engaging the darn thing. CRKTs liner locks seem to be pretty solid and trustworthy, but the LAWKS should go a long way toward alleving the concerns of those who are untrusting of liner locks in general.
 
It sounds like a really good idea. However I guess if the liver lock is properly made in the first place it isen't really necessary. I'd like to see the AXIS lock up close, and the Compression Lock too. I was able to twist the frame on my Endura enough to disengage the lock a few times. To it's credit, I was probably depressing the release a little, as I had a death grip on the thing.

I'm sure Sergiusz will post pics for you which will explain it a bit better.

However, in laymen terms all the Axis does is snap a spring loaded steel pin on the top spine side of the tang when it opens. This, of course, obstructs the blade from closing. Not rocket science really. You can go to the Benchmade website and it shows it in detail.

The Compression lock in simple terms (and I apologize to Spyderco and Sal Glesser for reducing it to such a derivative) is a reversed framelock/integral lock. Rather than the liner leaf snapping on the blade edge side of the tang, the Compression lock locks on the blade spine side of the tang. So the mechanics is similar to an integral lock, but the point of pressure is on the top side coincidentally like an Axis.

Sal Glesser explained in more detail at a Compression lock thread I created at the "bug" forum. Apparently, Spyderco believes there's an engineering advantage to putting the locking point on the opposite side compared to most integral lock designs like those you would find on the Sebenza, Pinnacle, S&W FL2, etc.

P.S. Before I get toasted by the Sebenzaphiles, let me point out that I only mentioned the Sebenza as an example. I'm not grouping the Sebenza with the FL2, etc. Sheesh. It's at the point where you gotta be real careful what you say about Sebenzas! ;)
 
FTC,

After such announcement I have no other choice but to do it :)

Nope, from mechanics standpoint they work very differently. In case of liner lock the relatively thin and long locking liner is loaded along its plane. Just try to put the thin and long ruler with one end vertically onto the table and press down with your palm the upper end – you will see how unstable it is. Of course this analogy is not quite accurate, the locking liner’s opposite end is not free. OK, put the same ruler with one end into the vise and try again.

In case of compression lock only the small part of locking liner is compressed between the blade tang and stop pin. Assuming that liner thickness is the same and the length of loaded part is at least 10-20 times lesser you can imagine how much more stable it should be. If you can’t imagine – try to compress your ruler in crosswise direction...

Here is the picture of stripped Vesuvius what might explain better than words.

Folks, I have pretty silly idea. We have excellent Joe Talmadge’s Sharpening FAQ here, maybe it would be worth to set up something like locking device FAQ?
 
Thanks from me too by the way Sergiusz! Great pics. :)

Thanks for clarifying my oversimplification on the compression lock. I was trying to explain it in visual terms, rather than mechanical, which obviously doesn't do it justice.

I'm pretty sure you can't kill someone for a comment from 7 months ago. Perhaps a beating at most, but killing is definitely right out after that long of a wait.:D

Pansy! Take from me, you can't coddle these heretics. We definitely have a "better late than never" scenario here. :D

Love your pictures. Could you please post more pix of the internal workings of the Compression Lock, throughout different stages??

Many a thanks!!! :)
 
Resurrecting a 3 year old thread? Afraid you won't have any luck because Sergiusz Mitin hasn't been active on this board since 2003.
