Before threshing, the farmer cuts loose the twine or straw that binds the sheaves with the sheaf-knife.
The blade usually consists of a piece of a scythe blade. It is therefore often slightly curved with a broad back, ending in a point. The length of the blade varies from 12 to 20 cm and is inserted into a straight handle (approx. 10-20 cm).
