Plural of graver: people who engrave, or tools used for engraving, or persons of serious demeanor.
From 'grave' (to carve or etch) via Old French 'graver', which comes from Latin 'gravis' (heavy) or potentially from Germanic roots meaning to scratch or cut.
The double meaning—both tool and person—shows how English often creates nouns from verbs; a graver could be someone holding a graving tool, making the word itself a snapshot of the craftsperson at work.
