Which mechanism caused bronze sickle effectiveness to drop, forcing frequent resharpening?

💡 Explanation

Bronze implements blunted quickly because continued use caused work hardening. This reduced malleability and flexibility, leading to brittle fracture of the cutting edge, therefore frequent resharpening became necessary; rather than edge deformation from creep or corrosion.
