Interesting Mechanisms and Designs on Knives

[Kaizen1]

Here's to hoping we'll see some interesting things come from this thread. The idea I have in mind is to share pics and some explanation about the thinking behind a design, a feature, etc., or something that may provide some insight into how a feature works. It doesn't have to be mind-blowing, but ideally it could at least be educational for people who are unfamiliar with the knife you're talking about. Here's my example:

Spyderco puts a slight curve (radiused) at the tang of the Military's liner lock in order to have better lock engagement at the lock interface.

In contrast, here's a close up of the lock interface of my Emerson Tiger. This is much more common to see on liner and frame lock blade tangs:

We've had a few similar threads in the past, here's one:

What I had in mind wouldn't be exclusive to locks, but any interesting feature on a knife - handle, blade, opening mechanism, carry features, etc. But if it feels uninteresting or like it's been done too much, then so be it

Take a look at the DPx HEST f if you want to see a multitude of built in features on a folder.

G&G Hawk probably has the highest number of unique-yet-functional designs. Nearly everything they produce is both a functional cutting tool and a mechanical showpiece. The MUDD, Hawk Lock, RAM lock, their unique playless OTF locking mechanism... I think they even designed the Kershaw ET and the boker Griploc. They do a lot of cool stuff.

The old Gerber Paul knife was an engineers favorite back in the day. It was a fast, one hand opening, locking knife.

I love the Paul lock. If for no other reason than it’s varied and destructive (on companies) interesting history. I’ll try and post a video of mine later this evening.

Paul lock in action.

Any body mention one of those chain drive things ?
I don't even know what they are called. Kind of before my time here but I saw them when I first driv up.
Were they Autos ?

Ratworx or something like that

Yup, Ratworx MRX... very nice action on those. I have the Chief in blue

Buck paradigm bolster lock. Moving the bolster pushes the spring load stop pin that is progressively wider in length. When open as shown the pin is pushed and centers the narrower part so the blade can open or close. With the bolster closed the wider part of the pin engages so the blade is locked.

Aww..why you gotta post that? I was blissfully unaware that I definitely need one of those...I foresee a WTB ad in my future

I was just gonna say the same. Awesome unpretentious father-son team doing great stuff. And I'm not a fan of most video shop tours, but this one was worthwhile:

I think the protech whisker is pretty awesome and unique. I've never held one......just YouTube videos. I can see myself acquiring one down the road.
