Where do I begin??

Well, At least as "tough" and resistant to chipping and edge rolling as 3V
At least as abrasion resistant as CPM Rex 121
Hardness. At least HRC 75-76
Carbides. Small enough to allow polishing to .1 micron without carbide "tear out.?
Sharpness. as least as sharp as a microtome

Any candidates???:D:p:D:p:D:p

Of course this may never be achieved, but it seems like a worthy goal to pursue!:):)

What say you, Larrin????
 
Gentlemen, saddle up your unicorns. We shall ride the rainbow bridge to the land of the fairies to find this new mystical material.:p

On a serious note I wonder if there are any alloys that are not iron based that would work better that we just haven't discovered yet? Iron itself is nothing special and is not that hard without carbon and quenching, and I feel like we've come pretty close to the limit of what steel can do.
 
Well there are all sorts of exotic alloys in the world of aerospace but they must be discounted since they are not clean sheet cutlery metal.

My unicorn’s in the shop, I’ll have to ride the mule...I’m anticipating heavy lifting so the mule may be the right choice...
 
BG42, cuts very well even when it won't shave or slice paper well which seem counter intuitive but that is my experience with my ARS folder.

Yeah well, just so long as I can sharpen it on the bottom of a coffee cup and get results like DeadboxHero DeadboxHero gets with his fancy dancy stones.

:D:D:D

With that level of precision it's very possible we may be a cleverly disguised android among us.

Don't say anything, he might catch on and then we're all doomed...

Now now. I find attention wh...I mean, "social media influencers" as insufferable as the next, but you really dont need a fancy super steel to stab them;)

My demands are that must be able to cleanly split a bullet AND a katana without edge damage and come in a smatchet shape.
 
No steel gets to 75hrc so don't worry :D

any steel at 75 hrc is not going to be tough, period... Larrin Larrin could easily list a bunch of reasons why, but you're better off reading his whole website
http://knifesteelnerds.com

tldr; ... something along the lines of 75 hrc = high carbide %'s = high brittleness = low toughness

the best bet, realistically, is some kind of a hybrid sea-shell approach like what they talk about in this article

We've got steels with cobalt, tungsten, nitrogen... How about a little silver in there? I mean, we are talking unicorns here. We might as well cover our bases with a little werewolf protection.
