I have a knife my father picked up in finland in the 1930's with the name johannes lauri roranicmr or could be rovanicmr engraved on the blade with a picture of a man on a sled being pulled by a caribou,also made in finland on the blade.The handle is bone with some design and etched caribou head.The sheath is leather with caribou fur on the front.The blade is a little over 6" and the knife a little over10 1/2".I'd appreciate any info anyone has!
