Weird/Uncommon Locking Mechanisms

One of the first things I tried to do as a kid when I got into designing knives was to try to design all sorts of new locking mechanisms, none of which worked or were practical. That travels over to my interest in knives now, where I find that knives with really weird or innovating locking mehanisms bring a whole new level of of cool to a knife.
So who knows of knives that fit the bill?
 
Two that were quite unique though no longer available were the CRKT Snap Lock and Hole In One.

Hole In One:

...and the Quartermaster General Lee (still in production in several variations):

CRKT has made a few odd locks for folders... others include the Fulcrum and the Rollock.
 
I really like Mike Read's lock on the PITS/Spyderco PITS. It's like the perfect version of a slipjoint.
 
I have an old Spyderco Meerkat with a Phantom lock. You kind of pinch the handle and push one scale forward and the other one back to unlock. Back in the days when I still loaned knives, nobody could ever figure out how to close it without help.

And the snap-fire and the Michael Walker Blade lock. Pretty much the only reason I ever bought a CRKT, it was a reasonable way to check out these mechanisms.

Lone Wolf brought back the Paul lock that Gerber used to produce for a while.

I'd love to get my hands on a Paul Lock! Didn't Lome Wolf make them for a while, as well?
 
Yup, the one in my pic is a Lone Wolf :) I see them pop up on the exchange occasionally for decent prices ;)

Grant & Gavin Hawk's strap lock on Buck Marksman 830...

That bottom knife looks like the most uncomfortable knife in the world to use... what the hell. Hot spots :confused:
 
I have to debate on the Fulcrum. It's a liner lock. It does have an unique/unusual opening method for sure.

Oh, I suppose you are right, it's more that the opening mechanism is unusual. Very fun to play with either way. [emoji51]
 
Spyderco Ball Bearing Lock has a high "pinball" cool factor and it is very easy to manipulate and quite secure, to boot!
 
I'm a fan of interesting mechanisms and have accumulated a few that no one's mentioned yet:

Pacific Cutlery, designed by Barry Wood.

Thumb Bolt sheath, designed by Blackie Collins and seen here on three AG Russell models.

Three different productions of the One Hand design by AG Russell.

Marbles Safety Folder, again designed by Blackie Collins. Turn the textured knob on the handle to release the blade.

Benchmark Rolox, later released as a CRKT model.

That Tri-Fold reminds me of the Cold Steel Triple Action, and a Perrin Tri-Folder... I really really love this kind of design. I think they're all a kind of 'jacobs ladder' design, right?
 
Except the Case TriFold doesn't flip, lock, or swing and wasn't designed for fast or one-hand opening.

Here are some images of it opened and closed.
