Scorper is a relatively obscure word, so there aren't many common synonyms for it. However, there are a few related terms that might be used in its place. One option is "engraving tool," which refers to a sharp object used for carving or cutting designs into a surface. Another possibility is "burin," which is a specific type of engraving tool with a pointed tip and a flat shaft. Finally, the word "scraper" might be used as a synonym for scorper, since both words describe tools used for removing material from a surface. While these options aren't exact synonyms, they offer alternatives for describing the same general concept.
