Every one of my working Knives is a Puukko.The steel in these knives are the best I have ever seen for holding an edge .I have with my Puukkos totally cut up 4 deer without sharpening .I have never seen another knife do this.I have a couple Karesuando Puukkos from Sweden and a few older Marttiini Finland knives thatare incredible.All have the classic Arctic Birch handles that I treat with Pine tar mix for preservation and grip with bloody hands in wet weather
