The knife was discovered at the Firse Sten tomb in Falköping and is in remarkably good condition, despite having been buried for thousands of years.
“It’s a knife blade which ends in a handle that looks like the throat and head of a horse,” said antiques expert Peter Jankavs from Falbygdens museum to Sveriges Radio.
The knife was found near the entrance to a 5,000-year-old tomb, although the knife itself is thought to be about 3,000-years-old, since the Stone Age burial site was later re-used by people from the Bronze Age.
The knife is so well preserved that its blade is still sharp.
“The edge is such that you can almost cut yourself on it,” said Jankavs.
The excavation of the site has been underway for the past two weeks and involves archaeologists from both Falbygden and Västergötland museums.
Following the conclusion of the dig, the artifacts will be put on display at Falbygden museum.
