The Srbosjek is a wheat sheaf knife that was originally manufactured in Germany for agricultural purposes.
Such a type of wheat sheaf knife was manufactured prior to and during World War II by German factory Gebrüder Gräfrath from Solingen under the trademark “Gräwiso”
The knife gained notoriety in the former Yugoslavian countries because it was used by the Croatian Ustashas during World War II for the killing of prisoners in the concentration camps of the Nazi-ultranationalist Independent State of Croatia, most notably the Jasenovac concentration camp.
This one was found with the blade all covered in grease, so it was not used.
