The Neolithic reaping knives from Egolzwil 3: A Mediterranean technical tradition in the late 5th millennium Swiss Neolithic

The study of the use-wear marks on the Neolithic reaping knives from the site of Egolzwil 3 (Switzerland, late fifth millennium cal BC) shows that these tools were used to reap cereals by cutting the stems near the ground. The stems were gathered together using the pointed distal end, held in the free hand and cut with the flint blade, in what we term a two-stage reaping method. These types of sickles or reaping knives are found at Neolithic sites in the northern Mediterranean (centre and north of the Iberian Peninsula, Provence in France and continental Italy) from the mid-sixth millennium, in the context of the early Neolithic Cardial Culture, and lasted until the early fourth millennium. Within the tradition of two-stage reaping knives, the Egolzwil type would have been adapted to reaping at a low height in very dense cereal fields. These tools show that the Neolithic groups in the Swiss central plain belonged to the circle of northern Mediterranean farming technical traditions, in their northernmost expression, in contact with the groups in south Germany who reaped with curved sickles whose flint elements were inserted obliquely.
