Laminated steel on frameback J.A. Hellberg?

[Fikira]

Hi,

One of my last purchases includes a frameback J.A. Hellberg
It has laminated steel as seen on pics, I first thought it wasn't real but
after polishing one side, the pattern didn't disappear, it even came more to life,
it's very hard steel and easy to get a incredible sharp edge! I have never had a razor that is SO SHARP,and easy to hone, really HHT 5!




When googling, I found no "laminated Swedish frameback's"

Does anyone know anything about them?

The razor has "Trolhätte Diamond steel" stamped on the spine,
I need to clean it up more, and put some new scales on it, couldn't wait to post this...

Thanks!
