A long, broad knife with an almost regular shape, made of flintstone, dating back to the Early Bronze Age. It is known by archaeologists as Canaanite knives, representing a continuation of the tradition of making long knives that began in the Late Stone Age and the Copper Age, continuing their production during the Early Bronze Age in the third and second millennia BC. It is believed that these knives were produced using a copper chisel by striking it on the edge of the flintstone core to produce a long blade. Initially, these knives were produced as weapons, such as arrowheads, and in the Copper Age, they served as sickles for harvesting grain. In the Early Bronze Age, these knives were inserted into a wooden board pulled by animals, similar to traditional plowing for grain extraction.
