Why did stone tools remain in use after copper and bronze tools appeared?

Stone tools remained in use long after the introduction of copper and bronze for several practical and socioeconomic reasons:

• Scarcity and Cost: Early metals were expensive, rare commodities often monopolized by kings, priests, and officials. Because metal was primarily diverted to the production of weapons for professional soldiers or luxury items for the elite, the common population—who often lived in simple huts—had little access to metal tools and continued to rely on traditional materials like stone, bone, and antler.12
• Material Limitations: While metal offered advantages such as toughness and the ability to be resharpened, stone remained superior in terms of edge sharpness. Furthermore, the transition to metal was not instantaneous; early metal tools were often simply copies of existing rock models, and it took time for societies to fully appreciate and master the unique possibilities of casting and metal plasticity.1
• Resource Distribution: The raw materials required for bronze, particularly tin, were geographically restricted and not universally available. Consequently, many communities lacked the necessary trade networks or local resources to transition fully to metal, maintaining stone-based technologies for much longer periods.23
