A sickle is a hand-held agricultural tool used for cutting crops, particularly grains and grasses. It features a curved blade that is sharp on the inside edge, allowing for efficient harvesting. Traditionally made from metal, sickles can also be found with wooden or plastic handles for better grip. The design of the sickle dates back thousands of years and has been used in various cultures around the world. It is often associated with agriculture and farming practices, playing a crucial role in the manual harvesting of crops before the advent of modern machinery.
