Gravers are tools that are used by engravers to carve designs or letters into wood, stone, metal, or other materials. There are many synonyms for the word "gravers" that can be used interchangeably depending on the context of the sentence. Some common synonyms include burins, chisels, gouges, scrapers, and etching needles. Burins are typically used to cut fine lines into hard surfaces, while chisels are used to cut into softer materials like wood.
