Traditional Norwegian "Viking" Knife

Up for consideration is a small knife that appears to be traditional Norwegian. This knife is similar to the Helle Viking knife. Knife features a burled wood handle with a 3 1/4" carbon steel blade. The blade is marked S.T. Tinn and shows some light patina. Sheath is traditional Norwegian with the button slit on the back side of the belt loop. I believe this knife was made by one of the many local knife makers of Norway. This is a very unusual piece and would make a nice addition to any Norwegian or Scandinavian knife collection.
