The Egyptians were not very experienced metalworkers, so most of their metal tools were imported from the north. Egypt’s strength was in chariots, not infantry. Using those fast chariots the Egyptians conquered many militarily inferior nations, including cities south of Egypt, which were very skilled in Bronze work. Greece, and the city-states around, manufactured much Bronze and Iron, and Egypt probably traded glasswork to them for the metal tools.
The Egyptians were skilled in Goldsmithing though, as seen in the Pharaoh’s burial masks.
