Helle triple laminate steel

I have a Helle Temagami and it has a blade of triple laminate steel, but I have yet to read what those 3 steels are. Does anyone know? I e-mailed them but they never answered.
I suspect one of them is Sandvik 12C27 but that is just conjecture on my part. I would appreciate it if anyone can give me some clues on the matter.

Cheers

Sorry, I didn’t include a shot of the Helle Temagami. Here it is. A three quarter tang in a Masur Birch handle. The name Temagami refers to the beutiful Northern Ontario region and were my old hunting and SCUBA diving grounds. I bought the knife for sentimental reasons because of its name and its beauty.

Gorgeous knife!
