Going home from a trip "to the source" (Northeast Finland this time) I have not yet cut anything with this knife. There are still some things I can tell.
It is not perfect. There are some little flaws in the blade. Near the tip there is a scratch that could be a result of a polishing wheel slipping and steel connecting a fast rolling tool. The polish has some places that are different than the rest of the blade. I am willing to forgive those, because otherwise the blade is great and those flaws I am willing to remedy myself.
The handle ergonomics feel great. Top notch. There is subtle swell in the handle that rests against your thumb muscle when you grip the knife. On the other side the handle narrows just enough for a solid grip. The handle is not too large, not too small. The surface of the handle is silky smooth, but not shiny. This differs from the Mauno Keränen Tommi-puukko that I have (little Tommi) and I like this more.
Blade is rhomboid, a bit more so than Mauno Keränen, allthough the shape is subtle. You can see it if you look closely. I will use this to roughly shape a walking stick that has been drying for more than a year now. That should be a good test, the stick is mountain ash.
