razor: [13] A razor is etymologically a ‘scraper’. The word was borrowed from Old French rasor, a derivative of raser ‘scrape, shave’ (from which English gets raze [16]). This in turn went back via Vulgar Latin *rasāre to Latin rādere ‘scrape’, source also of English abrade [17], erase, and possibly rascal. => abrade, erase, rascal
