noun
Rare historical term for a professional gambler, particularly one who frequented 鉄火場 (gambling dens) in the Edo period. Not used in modern Japanese; the common word for gambler is 博徒 (ばくと) or ギャンブラー.
「鉄火打ち」は、江戸時代の博打打ちを指す古い言葉だ。
鉄火打ち is an old word referring to a gambler in the Edo period.
Compound of 鉄火 (てっか, 'red-hot iron', also a term for gambling dens) and 打ち (うち, 'striking' or 'person who does something'). The exact derivation is uncertain, but it likely refers to someone who 'strikes' or plays in the 鉄火場.
