What is considered they most "exotic" super steel out there?

Let's define what super steel is first.

Currently super steel is defined as powder steel in general.

There is no definition of a supersteel, other that "Its a supersteel if someone calls it a supersteel."

It's not some metallurgical property like toughness. Are some powder steels called "supersteels" by some people? Yes. Are some non powder steels called "supersteels" by some people? Yes.
 
The most super steel (IMHO) is CPM S-150-V, but I am satisfied with S-125-V. S-110-V wore out the tester after 5mi. of cardboard, and it still shaved arm hair.

I'm didn't said Stellite is garbage. Its just won't hold an edge as good as a proper steel like D2.

But SM-100 is another story. I have bought a small knife from Eric Bono who is the owner of Summit Material, the maker of SM-100. It's brittle, poor edge holding and bend easily. For the price point it's should be considered as garbage.

And those maker are the one who actually had worked with the material not some armchair theorizing. All SM-100 are heat treated by Summit themself.

Rex121 is real brittle, the toughness is not much better than ceramic. I see no reason why it should be use on regular knife.

SM-100 is far brittle. Stop being a troll and grow up. Considering NASA has publicly released information talking about SM-100 and it's memory and extreme properties along with Ferrum Forge who uses SM-100 a lot your invalid opinion is worthless. As said before people have shown Stellite 6k to hold a better edge than D2. Are you blind or something? When are you going to use a HSS that is nearly a ceramic for chopping? Reallly? It's a HSS for CUTTING NOT CHOPPING. Educate yourself on the difference before talking.

Vancron 40. Its like cpm 10v and Vanax got it on and made a beast of a baby.

This sounds intriguing.

So far I have a Spyderco Maxamet Mule, a CPM REX76 B&T from Gary Creely and two B&T/Parers from Bluntcut Metalworks.

Though the BCMWs aren't in peculiar alloys, they are both Very stable with fairly high hardness (W2 & 52100 @ 64-65hrc). They do not chip or roll on raw or cooked beef or pork bones when boning out shoulders or other joint work and are both around .012 BTE.
 
Maxamet followed by vanax. I have a Tilt and have used it quite a bit and never had to sharpen it yet.
 
Ultrafort (maraging steel), can be aged to reach 60hrc, ULTRA TOUGH, stain resistant, has some wear resistance and is ULTRA EXPENSIVE.

Vanadis 4 extra, my favorite steel. Depending on heat treatment, can make a small slicer or a big chopper.

You have no clue on what you're talking about.

SM-100 memory properties is in it annealed state which has nothing to do when fully hardened. It weren't designed to be use at high hardness from the first place.

http://sb-specialty-metals.com/ Has some SM-100 sheet for sale. You can buy it at good price and make a knife out of it to see if it was any better than average steel and quit being an armchair scientist. SB-Special is the main distributor of SM-100 FYI.

A high reputation maker like Tom Krein, Micehal Burch and Sebastian Berenji even stated several times that they won't ever work with SM-100 again due to it's difficult to grind and won't hold an edge.

And what is the point of super fragile high speed steel for knife when there are plenty of steel that will cut as well while not being overly brittle?

It's pretty much a royal PITA to work with, which is why you don't see a lot of makers using it. I've had a custom maker flat refuse to use it. Also evidenced by the comments made by CM (in the orange) and AKS (in the green) above.


And me with the Rhino!
S110v ?? I was sent a sample and I made one knife, and one knife only outta it! ..............................:::::::::::It laughs at Ceramic Grinding belts and laughs even harder when I got to 120 grit and less for finishing! .... The Customer I made a 4" Drop point Hunter for outta of it raves about the edge rentention and grumbles about what a pain it is to sharpen on hand stones. ... I have told a friend of his to make one like the first one for him will be twice the cost!

what makes h1 a super steel?
Click to expand...

The fact that it will not rust.

Can somebody clear this up for me? Will H1 truly NEVER rust or is it just highly rust resistant? What about other nitrogen containing steels? Will they also never ever rust or is that just a property of H1?

Then secondly H1 is a steel that gets work hardened. That also makes it unique.

But basically H1 isn't a super steel in the sense it is super tough or super wear resistant, rather it is super corrosion resistant. (rustproof?)

According to wikipedia maraging steel doesn't hold an edge well. I am no expert and not sire ifnthat is true or not, just bringing it up.

H1 steel will rust. just needs enough time in the right conditions. but its very rust resistant. its also soft.

This one can reach 60hrc, so I'll assume it will hold an edge better than 4140 steel, maybe near S7, what for me is great, given its stain resistance and extreme toughness. I'll be using it in a chopper, so it's wear resistance will be more than enough.

Ultrafort I think it's a degree or two above regular maraging steels. I'm no expert, but there are conversations about it in some forums (in French, if I recall correctly).
Here you can read about it:

Rustproof that's all, the work hardening is wayyy over hyped.

Pretty sure the absolute best is Unobtanium. I used to have a knife with that ateel...it was Suh-weet!

Can you explain what work hardening means please? I've never heard of the term.

Work hardening is the strengthening of a metal by a "cold" process. It could be machining or milling, it could be hammering or shaping, or in this particular case sharpening/honing of the material produces the effect.
