검 (sword) is a long, bladed weapon used primarily for cutting or thrusting. It has been a significant tool in various cultures throughout history, often symbolizing honor and martial skill. Swords can vary in design, length, and materials, with notable types including the katana from Japan and the rapier from Europe. Swords are typically made of metal, with a hilt for gripping and a blade that can be straight or curved. They have been used in warfare, dueling, and as ceremonial objects. Today, swords are often collected as historical artifacts or used in martial arts practices like kendo and fencing.
