re Helle blade steel, pasted below is a post from the "knifeforums" board that I saved a while ago; hadn't seen this detail anywhere else, including the heat treatment of the edge layer all the way to 60 HRC. The Sandvik 12c27 steel used in the edge layer might be considered middle of the road by custom knife standards, but it is a known quantity and performs very well in the real world, & this is a company that has lots of experience with it.
FWIW I can certainly attest to the sharpness and edge-holding of the Helle laminated stainless. I made a maple-handled utility knife with "Turmann" blade that I use all the time for cutting leather, paper, garden chores, whatever. It is a real workhorse.
Hope this helps,
Andrew

Beautiful and good knives!
I have the "Ören" from Karesuando in carbon steel and have absolutely no complaints.
I own several Helle knives, i.e. the Fjellbit, the Jaktkniv, the Harding and a early Model of the Lappland which I bought back in the early 80's. The only difference to the actual model is the shorter blade, it has 7.1" istead of now 81/2". Whilst the other models are made of laminated steel, the Lappland is made of a solid piece of Sandvik 12C27. Not the ultimate cutlery steel, but,........ heat treated to a hardness of 58 HRC I cannot say anything bad about the steel, and I gave a lot of stress to this knive, believe me.
I was curious about the steel types they use in their laminated steels and I called Svein Helle, the owner of the company, by the way,..... a very nice guy, and he told me that the outer layers are 18/8 CrNi which is not hardenable but absolutely stainless and the inner layer is made of Sandvik 12C27, hardened to a final hardness of 60 HRC! Heck of edge holding, and easy to resharpen. All in all, wonderful knives for little money and every single piece is uniqe due to a lot of work that is done by hand.
cheers,
