One of my favourite and most used outdoorknives; a Kullervo Puukko made by Veikko Hakkarainen and sold through Kellam.
Although the knife originally has a zero edge Scandi grind, i keep a microbevel on 30 degrees inclusive on it using only the white sticks of a Spyderco Sharpmaker; not only is this edge a little stronger, maintaining it is also a piece of cake.
The carbon steel used gets extremely sharp and holds this edge very well; after an afternoon of cutting all sorts of fresh wood it is still able to shave the hair on the back of my hand.
The handle is made from real birchbark, gathered by Hakkarainen himself in the woods surrounding his home.
It feels somewhat velvety, is always warm to the touch and offers un unexpected good grip.
The deceptively simple oval shape offers a multitude of gripping positions, which all work very well without tiring your hand muscles too soon.
The Kullervo knife is a very well thought out little fixed blade, and it's definitely a keeper,
