I was ready to purchase a master hunter online and good thing I saw this photo from a customer. I've never seen 3V chip like this. Could it be the DLC process that made the steel brittle or the HT is just subpar?

 
Well one knife isn't exactly a large enough sample in which to base a whole purchase on. Just as one report of a good knife shouldn't be enough either. If I didn't buy a knife because of a solitary report of an issue I probably would never have owned a knife period. Even if it was an issue on a number of knives I think more info is needed before determining anything from just a photo.
 
Yikes. From the title I was expecting much more minor damage. That's a good-sized chunk.
 
Someone could come in and correct me but I believe Cold Steel heat treats it's 3v to a high rockwell (61 to 62 I thought?)... so I believe they were going more for edge retention than toughness. That being said, 3v should still be plenty tough and in order to chip like that some pretty hard lateral force must have been applied.

Without knowing the backstory this is just hearsay

I don't know what you're talking about bro-siff. This is clearly a picture of a CS MH with a big chunk out of its cutting edge. Obviously, every CS MH will do this immediately upon first use, so what more evidence do you need?? I mean, do you need to see this on Wikipedia before you'll believe it?
 
Typical of a chop ,then twist ,which will put a halfmoon notch in the blade !! Batoning again ?
My original master hunter doesn't have notches ,but then it's never been abused !!

CPM3V is at it's best at 62rc.Even at 65 it's still tough as hell.

Exactly For all we know this blade could've been shot with a rifle round.

Quote from the customer who bought the knife.

I bought this knife and was pretty excited for the supposed quality at this price. The edge was super sharp and cut through wood to make feather sticks like butter. Edge seemed to stay sharp. I thought I had found my new favorite knife.

Then I used it to baton through a 2 inch piece of wood which wasn't even a hard wood and a big chunk of the blade chipped off where even reprofiling the blade would be hard. And if somehow you were able to reprofile the blade there's even a crack forming in the middle of the blade which would no doubt lead it to breaking right in half at some point.

Such a disappointment. This can't be real 3V or they are using some fancy marketing to burn people. Maybe they just have the very edge as 3V but the rest isn't. Who the hell knows...but I have some cheap rat tail $15 Mora which was stainless steel and not even carbon steel that I used to baton through the same wood and had zero problems.

Such a HUGE disappointment.

Probably heat treat.The best steel in the world with a lousy HT might as well be Pakistani pot steel.If that's what happened...

One time, I bought 1,000 rounds of .45acp ammo. The first bullet I fired was a dud, so I threw the remaining 999 rounds in the trash.
 
I'm not a CS fan at all, but let me get this straight....

We have an anonymous and unconfirmed account of someone trying to bash a hunting knife through a hunk of unidentified wood that could have had any number of knots, and no mention of the temperature at all. So it's totally possible that this thin edged slicer hit a rock hard, frozen solid, sap filled knot and lost a chunk.

And we're going to make a judgment based on this unverifiable statement from the unknown person?

Even if it was as perfectly innocuous as it sounds, and the story checks out, it's still only one example (no statistical validity) and is still an example of using the wrong tool for the job.
 
Mine chipped, nothing like the one pictured, but much worse than other knives I have with similar geometry and supposedly lessor steel, doing identical tasks.
The good news is, it sharpened out easy...
 
2 inch branch and two inch piece of wood are two very different things. Wood makes me thing lumber which can have nails as well

It's one of two things:

Improper HT
User Error

I have used 3V a ton (all custom knives) and I can tell you from my experience that you are not going to cause that kinda damage driving it through wood, but that's also a story we can't really verify either...

I am never going to be surprised by large manufactures like CS maybe not getting a batch of steel right once in a while, and I also wouldn't be surprised if that guy tried to cut his Spyderco diamond rod in half because he thought 3V was just that good.
