If I would have to define a typical basic form of Finnish puukko, this would be the result. Curly birch, carbon steel, and so called scandi grind.
This type of knives are called maasepänpuukko, translating as village smith's knife, a knife made by a village smith. It has all the things a knife needs; a handle, blade, and sheath or blade cover. Nothing else, no decorations, no elegant curves or artistic views, or other "unnecessary" things. In my opinion a maasepänpuukko loses it's attraction if it's finish is honed to perfection. It doesn't mean it has to be made quickly without any attention, but being microscope proof isn't what a maasepän puukko is about.
If you see an old puukko in this style, used and sharpened a lot, it speaks history and life. From time when tools were valuable items, and used for a lifetime and more. Very different from modern world when you can just take a few Euro knife, use it without any care, and throw it away when it get's dull. An old finnish common man's puukko was used for pretty much everything where a knife was needed. Whittling, eating, cutting, butchering, cleaning game and fish, carving etc. It's not the very best option for any specific work, but you can get all everyday tasks done with it.
