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 have been used for thousands of years in various cultures around the world. Sickles are often associated with agriculture and farming practices, especially in regions where manual labor is common. They are also symbolic in various contexts, such as in the emblem of communism, where a sickle represents the working class and agricultural laborers.
