a folded-steel argument that ends conversations and centuries-old debates about who's leaving the room
means A katana is a curved, single-edged Japanese sword, traditionally worn by samurai with the cutting edge up, prized for its slicing power and elegant blade.
from From Japanese 刀 (katana), "sword" or "single-edged blade" — the kun'yomi, or native Japanese reading, of a character also read "tō" in Sino-Japanese compounds. The word entered English in the late 19th or early 20th century as Western fascination with samurai culture grew. The blade's signature curve was no aesthetic whim: it emerged from the forging process, where differential hardening of the steel — a hard edge over a softer spine — caused the metal to bow as it quenched and cooled.
