Round knives are versatile cutting tools featuring a circular blade that serves multiple functions across various industries. The main functions of round knives include slicing, trimming, and cutting through materials like paper, fabric, and plastic. Technological features of these knives typically involve a sturdy, rotating blade mounted on a handle, allowing for smooth and continuous cutting. The blade's edge is often sharpened on both sides to ensure efficiency and is replaceable when it becomes dull. These knives are engineered for precision and can be used in both manual and automated systems. Applications of round knives are widespread, ranging from the manufacturing of packaging materials to the processing of textiles and leather goods.
