Any Kershaw/ZT made in CPM-M4?

Was there ever any Kershaw's made in CPM-M4? I am thinking no, but just wanted to use a lifeline and ask the audience.

I hope there will be.
 
Oh man a ZT0200 would be absolutely awesome in CPM M4. Corrosion resistance takes a back seat when you have a perfect balance of wear resistance, strength, and toughness.
 
Don't think corrosion is an issue on a DLC'd blade. Then you only have to worry about the edge.

It's no worse than D2 on that regard IMO.

DLC does nothing to help with corrosion.

I've never noticed any rust bubbles under the diamondlike coating on my Kershaw knives..... I don't see how you can think what you typed unless you think DLC means "downloadable content" or something equally different from "diamondlike coating." (Alternatively "Diamondlike carbon," though I have seen the term DLC applied to carbon-tungsten diamondlike coatings as well.)

Anecdotally, there may be cases of failure. But note that not all DLC is the same, much as not all electroless nickel, boron, melonite, or hard chrome firearm finishes are the same. Defects or improper application will compromise any finish.

These articles suggest otherwise - that DLC can be used to inhibit corrosion

I've always felt it assists with corrosion. Can't say I've ever seen much for DLC blades coming back through warranty due to any rust. Most steels we use that are really susceptible to corrosion we most always talk about coating them. Just our experience.

The articles I linked involved tests on DLC coated steel immersed in various corrosive solutions over extended periods of time (in hydrochloric acid, salt, and hydrogen sulfide exposure, etc) and they've obtained their conclusions via the scientific method. The links you provided are an example of anecdotal evidence. As I said, not all finishes of the same type are equal. A lot depends on the substrate the DLC is applied to on top of the steel itself. Again, if a finish is not applied properly, murphy happens. S&W did a batch of M&P's a while back that rusted right through the Melonite, doesn't mean Melonite is not a corrosion resistant finish now does it?

This, any physical barrier that reduces exposure of the steel surface will resist corrosion.
 
Ok it may offer some protection from rust but it is far from turning M4 into H1.
 
I have never had an issue with corrosion on my CPM M4 uncoated blades - I like CPM M4 a lot and currently have one knife with that steel (it is coated black though) but I am really good with Elmax anyway! :)

I do live in a low humidity locale though. In fact, in all my years as a knife enthusiast, I have never had even a spec develop on any knife I have ever owned so far . . .

And it is somewhat a known fact in some circles that some coatings will enhance corrosion. Probably more because of the prep work the steel has to go through than the coating itself. I would assume it may be "roughing" of the blade surface since I've heard it said that blasted blade steel also tends to spot easier than satin or SW finishes.

In the Strider world, it's a generally accepted fact that the SW blades are much less apt to develop a corrosion problem that their coated blades.

Hmm, this thread has turned up some interesting info. I guess the Stonewashed vs DLC debate will always continue. . .

I have a gayle bradley and like it but am trying to get rid other buggy brands and stick to Kershaw, its just a little hole left to fill now. S110V fills the gap and is pretty exclusive but I'd love to see a special edition M4, in any knife, as long as its a great slicer. Seems others might be interested too, too bad I am not going to be buying my own 500 any time soon.

I recently got a Lahar, great polish or brushing on the blade, my last VG-10's of the other guys will be disposed of soon.

No doubt. But to be honest, no coating on carbon or stainless out there is going to offer as much protection as a speciality highly-rust resistant alloy - which can still be coated in the end. For one, the edge on a coated blade is always a liability.
