I'm always reading that many of his knives use his patented Self-Lock, but there is never an explanation of what it is and how it works. Can anyone shed some light on this?

Also curious about the Blackie Collins Bolt Action Lock which is rumored to be used in the Sage III. Can anyone explain it?

Thanks.

It is pretty cool!

If you look at the info in the link that DavidZ provided, you can see that the locking cam is integrated in the pivot. To unlock, you push on the base of the blade under the pivot to release the locking mechanism. It is very smooth and seems to be very solid.

I have a Sawby CU folder and a Bradshaw folder that use it. The lock is a very interesting design. It seems to make the lock as solid as the pivot with very little room for any extraneous material to get into it.
 
Looks to me like a man could go broke just putting together a collection of the various locking systems,
 
I have a Bradshaw with the self lock and it's one of my favorite knives. It really is a slick lock.

Thanks for posting that link. I had it explained to me but pictures help allot.

Not to high jack this thread, but it is funny you should mention this. Way back in the mid 70's, I started a collection of various folder mechanisms. I figured that I would have to get a dozen or so, and then I would have a complete collection. I was ever so wrong. The list goes on forever. My collecting then took another direction, and I sold most of them off. I am currently compiling a list with pictorial examples of different locks, so I can start a thread about it here. Anyway, a Blackie Collins bolt action by Gerber was in that accumulation. Blackie Collins is an absolute design genius!
 
It is truly an ambidextrous lock. I have a Scott Sawby Combat Utility, with CF handle scales. It is fantastic. It is also VERY thin!

When I started with knives, I considered guiding my collection based, at least partly, on exploring as many different locks as possible. I quickly gave up on that idea, but for reasons other than there being too many to possibly acquire. I didn't realize there were a lot like you say. I thought I could maybe list them on the fingers on both my hands:

--back lock
--liner lock
--frame lock
--compression lock
--ball and cage lock
--axis lock
--bolt action lock
--self lock
--ram safe lock (CS Pocket Bushman)
--ring lock? (Opinels)
--button lock
--levitator lock (BM Benchmite)
--pin lock? (Extrema Ratio)


Isn't that it?:confused: Of course there's more, but really, how many more can there actually be? I'm looking forward to your list with pictures.

I also considered collecting with a diversity of blade steels as a guiding principle. And I'm still trying that to some degree, but it gets very expensive.
 
I have one and its cool to operate. To release it, there is a bump right near the choil (imagine a flipper that is almost cut off). Well push that bump upward and the whole blade moves up a 1/8 of an inch. Then it can be rotated closed.

I think the mechanism is internal to the pivot area where it is a circle and a slot below it. The pin is flat on two sides and when it falls into the slot the blade is locked in place. Push the blade up on the bottom into the circular area and the blade rotates shut.
