Ernst Skofteland said he asked a team of archaeologists digging on a farm near his home to look at the sword, which he discovered at the side of a lumber road in a forest area four years ago, and they told him it dates from around 1100-900 B.C., Aftenposten reported Friday.
"When they told me how old it was, I thought they were kidding me," Skofteland said. He said he turned the sword over to government authorities for study.
Experts said about 20 similar swords have been discovered in Norway.
