器械
きかい · kikai · JLPT N3 · noun
instrument
🩺🔧 器械 = vessel/tool + contraption: the tools themselves, not the machine
器 means a vessel or tool and 械 means a device or contraption. It sounds exactly like 機械 (kikai, machine), so tell them apart by kanji: 器械 is for hand-held instruments and apparatus, as in medical 医療器械 or gymnastics 器械体操.
