I like to hear why ? My fotos are just example of design, materials could vary depending where you use yours puukko. By the way; this first one went to Australia where one member of this forum use it.

Fällkniven type knives are very familiar to me but the big question is geometry of blade. You could do with puukko all same works as any knife and then many such works whose are allmost impossible to do with, for example, this type Fällkniven which is good when skinning or cutting somethig but that´s it.

When making puukko you could use same high tech material which Fällkniven has i.e. you could sharpen yours puukko as good as those knives. Puukko is a scandinavian design and way to do a good allround knife.

So when talking anything about puukko you should first buy one high quality hand made one and then test it. After that yours comments are valid.

By the way, has any of yours tested this puukko: https://www.spyderco.com/catalog/details/FB28GBN/Spyderco-Puukko-G-10/812
