The Hindsgavl Dagger (Danish: Hindsgavldolken), found in 1886 on the Danish island of Fænø, then owned by Hindsgavl Manor on Funen, hence the name, is one of the finest examples of a so-called fishtail flint dagger from the end of the Nordic Stone Age.

The dagger was discovered in 1867 by a little boy in a field on the island of Fænø, then part of the Hindsgavl Manor.

It is an example of a so-called fishtail dagger, named for the shape of the handle.

The design was inspired by imported bronze daggers, which had already started to appear on the Scandinavian market.

Production of flint daggers continued well into the Nordic Bronze Age.
