"칼" is the Korean word for "knife." It is a tool used for cutting, slicing, and chopping various materials, especially food. Knives come in different shapes and sizes, each designed for specific tasks, such as a chef's knife for cooking or a paring knife for peeling fruits and vegetables. In addition to culinary uses, knives have historical significance in many cultures. They have been used as weapons and tools throughout history. The design and craftsmanship of knives can vary widely, with some being considered art pieces, such as traditional 일본 칼 (Japanese knives) or 한국 칼 (Korean knives).
