Does a gold knife or a shining silver sword have the same symbolic status as iron, which is associated with shortening life?

This Torah study examines the question: Does a gold knife or a shining silver sword have the same symbolic status as iron, which is associated with shortening life? The canonical Hebrew discussion develops the issue through the weekly Torah portion and the sources cited there, preserving the distinctions, tensions and practical implications that belong to the source itself. This localized layer is designed for study and discovery; it does not add a new halakhic, medical, legal, historical or empirical ruling beyond the canonical Hebrew source.
