Pretty good chance they burned the edge when they sharpened it.

Is there anything I can do about a burned edge if it is that and not the steel? Grind the edge down a mm or two then reproduce the profile?

Edit: I will not be a whingey jerk and hold you or anyone else responsible for any advice given to me about this issue.

Just keep sharpening manually. If it’s a burned edge you’ll get to good steel eventually.
Grinding or sharpening with power tools will just get you more burned edge.

I just spent the last few hours in a painkiller-induced sharpening haze. Even cleaned up some serrations I’ve been meaning to get to. I just cannot get used to this one particular knife’s cpm-154. I don’t know what it is. It sharpens ok, doesn’t get crazy sharp, but I feel like it dulls if I use even one time. I love everything about this knife otherwise but the steel drives me absolutely nuts. It is always dull. What the heck is going on? Does anyone else have any experiences with this steel? Is this a cpm-154 thing or a heat treat thing?

It is not the steel. It is a proven good steel and I have a kitchen knife in that steel that I use daily. It definitely holds an edge.

Hand sharpen it and it should be fine, assuming that it is really a burnt edge and not a heat treatment.

Speaking of small world, I was at the US Embassy in Saigon and ran into a guy I graduated high school with. He was an admiral in the Navy working on a big project there. Shocked to see just how small this world is!

That’s awesome. I have several of these, but here’s a quick one…

My son worked at Disney in Florida for a while. They have a whole underground tunnel system for employees to move around the park… and pop out like moles I guess.

Anyway, he’s walking in the tunnel one day on the way to his job, and he recognizes a girl he went to high school with in California. Underneath Disney. Craziness.

I wonder if that's the problem with my benchmade mini presidio 2?
Wonderful knife but the S30v has micro chips in it from cutting cable ties, cardboard, opening boxes etc...it's pretty unimpressive

... That might just be S30V....

The most overhyped "super steel" that ultimately led me away from those high chromium super high carbide steels that stay sharp forever in light cardboard cutting tests but actually suck in reality.

I'm not even 100% sure what this is. It appears to be paper-based and it came out of some old Westinghouse electrical switchgear, but I'm not sure it's micarta it could be melamine. I've used it before and it works good. This is from the second half of a big piece that I had. I've been hoarding it for a little while.
