This is a mincing knife used in the New Zealand whaling industry in the mid-1800s. It is made from iron and has two wooden handles. It is 93 centimetres long and 9 centimetres wide.
This asset demonstrates a type of technology used in the whaling industry in Australia and New Zealand in the mid-1800s - the mincing knife was used to cut the blubber into squares so that it could be boiled down in iron trypots to extract the oil, which was used mainly for the lubrication of machine parts and fuel for lamps.
It indicates that the whaling industry was operating in the mid-1800s in New Zealand waters - whaling was New Zealand's first significant industry and an important point of early contact between Mäori and Europeans.
It illustrates that the rendering process in the mid-1800s was physically very demanding - the knife was used by a single person.
