Two Ancient Egyptian Predynastic Flint Blades Circa 4000–3000 B.C. A pair of finely worked Predynastic Egyptian flint blades, skillfully knapped from high-quality honey and light brown flint. The larger blade is elongated with a gently tapering form, displaying careful bifacial flaking and visible ripple marks from controlled percussion and pressure techniques. Its edges are irregularly serrated from retouch, suggesting use as a cutting implement. The second blade is more rectilinear in form, featuring a distinctive straight profile with finely denticulated (serrated) edges along both sides. The surface retains a smooth, slightly glossy patina, with subtle color variation characteristic of aged desert flint. Both pieces demonstrate the advanced lithic craftsmanship of Predynastic Egypt, when stone tools reached a high level of refinement prior to the widespread adoption of metal. Such blades were essential tools in daily life, used for cutting organic materials, food preparation, and craft activities. Dimensions: 7.3 cm and 7.1 cm. Provenance: found in Egypt in 1930s. Ex Swedish Egyptologist collection, 1990s. Later in European collections.
