刀 (katana) typically refers to a curved, single-edged blade, especially Japanese swords. 剣 (ken) usually refers to a straight, double-edged blade, often associated with Western or fantasy swords. In everyday speech, 刀 is more common for physical swords, while 剣 is used in compounds and formal contexts. When in doubt, 刀 is a safe default for a physical sword.
In English, 'sword' can be used loosely (e.g., 'sword fight'). In Japanese, specify the type if possible. For example, a samurai sword fight is チャンバラ (chanbara) or 殺陣 (tate), not just 刀の戦い.
