A whaling instrument known as a Flensing tool.
Flensing is the removing of the blubber or outer integument of whales, separating it from the animal's meat.
It was also known as 'cutting in' or 'flinching'.
Processing the blubber into whale oil was the key step that transformed a whale carcass into a stable, transportable commodity. It was an important part of the history of whaling.
