Very easy to process (little tool wear during processing)
Water jet cutting and laser cutting possible without any problems.
Very good for resharpening
These three points suggest this steel isn't very wear resistand
Very good corrosion resistance (similar to powder metallurgical steel)
Being a pm steel has no effect on the corrosion resistance.

As Sharp Bits pointed out we can already determine it's not a pm steel
I only saw one review of a knife with hybrid cryo steel and the reviewer rated the corrosion resistance as mediocre.
AEB-L could be a good suspect
But I'm affraid the mystery steel as a lower corrosion resistance (based on only one revieuw)
There is a video with the owners of Midgards messers with folks from Böhler.
They seem to suggest 61hrc for a folder and only 58, 59 for a fixed blade. AEB-L can have a higher hrc for a fixed blade.
I'm now thinking the full name of the steel is: Viking hybrid cryo.
Böhler has a chipper steel called Viking
Viking (A8mod, K329), maybe it's based on this steel?
