This chapter presents the results of my use-wear analysis, applied to Shang weapons for the first time using the weaponry collection in the British Museum, proving the applicability of the method to both Chinese weapons and museum collections without archaeological provenance. I develop and define a set of terminology to describe various marks observed on late Shang weapons, such as notches, nicks, chips, and scratches, which are then contextualized against the phases of weapon biographies – production process, consumption, treatment, and change during deposition and post-recovery interventions. After applying both macro- and micro-level examinations, I evaluate their effectiveness and assess their practicality for future application.
