This is Steel-Ceramic - steel with small amount of microscopic particles of aluminium oxid as I understand (may be some oter abrasive). It is like sandpaper but with sand is embeded in steel.

This is report from Russin Knife Show Klinok 2005 blades are on 9th photoes and next is maker of this blades Vladimir Petrik.

He is also known for his bubble steel - steel with microscopic bubles inside like Wispa chocolate, claimed to be lightweight less fragile, because cracks stop on closest buble.

However I do not understand this both technologies so this is what I got so far.

Thanks, Vassili.
 
Aluminum oxide isn't ceramic.

But the idea behind is intriguing - imbedding macro-carbides into the steel matrix so to speak. I doubt that you could easily resharpen it in the field though.

Would make an interesting edge profile. How hard is the steel with the particles embeddedin it and how large are the particles?

I guess he meant "alumina" ceramics. IIRC, it's the stuff used by Spyderco for its gritstones at the Sharpmaker 204.
OTOH, doesn't Boker did something similar with Ceratitan? Small ceramic grains embedded in titanium.

All I know - I already told. This steel puzzling me also. Like is it more fragile - because of this particles? This is the only maker who doing this so far and it is hard to get from abroad.

Aluminium Oxid as I remember from school is the major part of clay and ceramic. Aluminium Oxide particles is abrasive part of Spyderco ceramic stones.

Thanks, Vassili.
 
Is there any way those blades could be put up for a pass around. It would be interesting to see how they perform.

I have forwarded your request to his old e-mail. Hope he'll replay to you.

Thanks, Vassili.
