Cold Steel New Atlas Lock Video

CS always had very strong locks and I never doubt their reliability and quality. However, I don’t like “exposed” locks, sort of speak… I know, this one, as well as the Shark lock and all other new flavors they came up with, are very hard, if not impossible to disengage by accident, but still small chance exists as with any other types of locks.
IMO the Triad lock is probably the more secure (BEST !!!) CS lock (money can buy !) and I would prefer those over the newly developed… They are slightly stiff to open but there is very easy cure for this without actually to sacrifice the reliability of the lock, so Triad will still be my choice, even this one looks very interesting :cool::thumbsup:
 
Kinda reminds me of their old RAM lock that was on their pocket guillotine...er, pocket bushman ;)

However, on that lock, the rearward spring was driving a wedge forward to engage the blade so that the tang was wedged up against a folded steel one-piece handle.

Very strong, very scary to close.

Very scary to close one handed when you are trying to open a bag of peat moss, dump the dirt and shove a flower in the hole you made.

I'm a bit gun shy. My pinkie was just bitten really hard by an Axis automatic today. The PB always seemed like a knife that was easy to close carefully and with attention but one that would slam shut on you if you treated it like a regular folding knife. I lost a sliver of my finger to one about 15 years ago due to treating it as such.

In short, the PB is a great compromise to a fixed blade if you are picking one to take a folder in its place. However, it is NOT forgiving to those wanting to mindlessly close their knife. Weird pull cord lanyard, slippery handle, blade that falls closed like a bus crash.

yeah naw its a two hander closer.

Sorry about the finger. It sucks when you get yourself good…

One thing that was curious to me - why no proper Cold Steel spine whacks with a 30 pound weight swing?? Just some light whacks (with someone’s hand in the absolute wrong place for a spine whack).

Wonder if it’s got a whacking problem?

I thought the same thing. I’d say the Kudu looks scarier to close though.
 
Mechanically, it's a Triad lock, rotated 90 degrees. Yes, it looks different enough, but you're still transferring force from the blade tang, through a lock bar, to a pin. Maybe two pins, but you get the idea.

I remember Boeing (maybe) built a really gollywog computer program that could simulate mechanical stress on components, then represent it as a color map, superimposed over the test piece. I would like to see this lock simulated in there, to see where the force transfer takes place.

Bladeforums is going to motivate me to learn mechanical engineering. Good Lord, what's wrong with me?
 
The part where it wiggles & he just simply tightens it is awesome, brilliant marketing.
 
Looks like a great lock and a lot easier to use than the backlock style actuation of the Tri-Ad.
The one comment I will make is I hope they can design it with an extra oversized stop pin to complement the super strong lock when scaled up for larger blades.
Chopping wood (I was hacking through a few branches with my Hold Out 1 on a hike yesterday) is extremely hard on the stop pin and a lot of the "lock wear" that people imagine happening in hard use scenarios is actually the stop pin being hammered out of shape.

I mean, it’s not THAT different in interface even. They basically took the Sharklock and opened the top, so that the cut out encapsulates the stop pin as well. It’s damn similar to Demko’s design.

Similar yes, but the key difference as I see it is how the Atlas also wedges under the stop pin, which the Sharklock doesn't. So the Sharklock has one pin (not counting the back one that anchors the spring), which is much further back. While the Atlas has 2 pins much closer to the blade.

Don't do it . . . IT'S A TRAP! Plus, you forget everything you learned in about 23 minutes after you graduate.

No fear! I would crash and burn on the math part. But I can pick up a fair bit, just by reading a textbook. It's not as if Cold Steel's "tests" are scienticious, anyway. But knowing how to tell where the weight transfers, and some dead reckoning formulas, would take a lot of mystery out of these kinds of presentations. And I do like killing a mystery.

The math is the first thing to go! I got disgusted with myself years ago because the best I could do was very simple calculus. Eventually it got so bad that a few years I repeated a bunch of math courses online to rejuvenate my tired old brain. It worked well for a while, but now it's fading again. If you don't use it, you lose it.
 
rhino rhino , if you've done the engineering thing, maybe you can help? Am I correct in assuming that during their hanging weight test, all the weight was transferred to the second-in-line stop pin?

I don't know! I didn't pay close enough attention to the diagram or the video. I am lazy.

Looking at the image of the lock again, my best SWAG (Scientific Wild A** Guess) is that most of the force is probably borne by the forward pin, but the rear pin probably has a significant load as well.

Edit: looked again. For some reason I though the locking bar could pivot, but it doesn't look like it can. That suggests that the load would be fairly evenly distributed on both pins.

My calculus literacy stopped at about basic derivatives. Integrals wrecked me. Edicational YouTube channels helped a bit though. Great for refreshers.

Does that mean it could potentially take more punishment than the Tri-Ad lock? Since the load is distributed on two pins instead of one?
