The forum seems to be somehow incompatible with Google. Those links work anyway...Jani, you have got to get it in gear with your pictures before it goes anywhere.
Here is how that Kellokoski 14/2 looks like after some cleaning.
Sharpened like a razorblade and old handle looks also nice.

I see these rehabbed by users native to the regions in which these would have been a local standard. I hate to remove more material from a tool than necessary to get it functioning again but as that general blade shape wears, they seem to become quite thick. What I don't see much of is users removing lots of material from/up the cheeks of the axes higher up to reprofile them (including myself) - that is probably out of respect or preservation of the axe?
But here's a couple of curious images of an old Billnas(please disregard the numbers in image names,they don't refer to it being 12-1 or 2 or even 12 at all,just image numbering).
Could this had been one of the factory methods of reshaping blade profile?
A part of an equation to keep in mind is that,during the earlier Industrial era(and before,of course),forging the blade out/re-steeling the bit was common practice(as we all here know).
I often wondered what that fact alone has contributed to the blade shape/thickness/et c. of a Finnish axe,as in how much of it was a provision for the future reshaping?

(as an aside,kinda back to Square_peg's phanthom bevel concept...).

Very curious! Certainly looks like the body was pushed out to the bit. Perhaps done with a fly press or forging press.
Do you mean like the Japanese do on plane and chisel blades?(Seems like a good way to ease both the chopping,and the hewing action,as well as simplify the sharpening of those large hewing surfaces(the back side).
