Hi there!
The swedish and finnish (and I guess norwegian ones as well)traditional knives are quite similar looking and are in many cases known as puukkos in USA. In Sweden these knives are often called "lapp-kniv", (or lapp-knives).
Here in Gellivare in Lappland, northern Sweden almost every kid in school has a chance to make his/her own knife at the woodworking lessons in junior high. So did I, and my grandfather further educated me in the art of making such knives.
The typical Puukkoo, or lapp-knife, for me has a slender carbon steel, straight point blade without secondary bevel. The handle consists of natural materials, such as birch wood and reindeer horn, and has no guard. The sheath is made of leather, or a combination of wood and leather.
I warmly recommend Bo Bergman's book "Knifemaking" for those who are interested in making their own traditional scandinavian knife.
