S90v blade damage, didn't expect this! Photo.

I would like a D2 machete or 10" chopper....coincidentally. Haven't researched yet. Part of me wonders what the heck I would actually use it for.

If only they made a portable water jet, I'd want one too! ;)

In all seriousness, the toughest knife I have ever owned is a D2 Kershaw Outcast...it somehow ended up at 64-65 RC. I tried EVERYTHING to sharpen it....sent it to Richard_J for his crazy sharpening skills on his big belt sander....a few belts later it came back crazy sharp. I've chopped sandstone with it and BARELY rolled the edge. It's got some Jedi magic in it or something.

The ability to chop through a brick is more due to edge geometry than steel "toughness".
 
Post- convex regrind, it worked pretty good for chopping down a 20ft palm; they aren't exactly an easy project. A handsaw didn't work, a chainsaw was kind of scary because of the layers of hard outer spines and pulpy wet interior....And an ax was a complete failure (bounce, bounce!).

It took a while, and yes I did get completely worn the F out. It would still "saw" through printer paper, and 10 minutes on my small 1x32 belt sander and paper wheel...razor sharp again. Find one if you can, just expect a serious reprofile job.
 
I would not personally use a CPM S90v blade in this manner, but I think it faired well.
 
There are micro chips that didn't photograph well. But maybe that's what "dull" looks line under 8x. I don't have a lot of experience with looking at blades under magnification

AmericanEDC, there are different causes of dullness and the microchips certainly are one. In fact, they are what is expected with this steel, at this hardness, doing what it was doing, and so on.

Don't take any fraternal ribbing personal. You bought an excellent knife, used it well, took excellent photos of it and discussed it here exactly where and how you should have. You have added to the common knowledge base, at least for me anyway.

Thank you and please continue with such threads in the future, hopefully with more photographs which can explain things better than words.

Well done all around in fact.

The DMT Course stone arrived and I no longer have microchips in my blade. It only took me a couple of minutes to get the right angle, with the help of a sharpie. Fairly light pressure later maybe a total of 30 strokes each side and they were gone. At 45 microns/325 grit I would say the blade is just shy of factory sharp. I will wait for the Fine stone before continuing on. I haven't looked up the blade geometry yet but my guess is these bevels are 23° Or similar? This is my first freehand sharpening but I seem to be keeping it consistent because it's coming off the Stone quite sharp. I'm already impressed by this DMT product.
