the only tool that perfects you by subtraction, one careless second from drawing blood
means A sharp-edged tool used for shaving or cutting hair, prized for its keen blade.
from From Old French 'rasor,' from 'raser' meaning to scrape or shave, which traces back to Latin 'radere,' 'to scrape, scratch, or shave off' — the same root that gives us 'erase' (to scrape away) and 'abrasive.' So a razor is, quite literally, a scraper-away, named for what it removes rather than what it leaves behind.
