Blade is the 'hero' name of Marvel comics half-vampire, vampire-hunter, protagonist Eric Brooks. He was portrayed by actor Wesley Snipes in the 'Blade' film trilogy and Kirk "Sticky Fingaz" Jones in the television adaptation.
It was most commonly used before the 20th century, though not nearly as common as the top names of the late Edo period (1603-1868), e.g. Kiku. Nowadays, it is very uncommonly to rarely used.
