Stapling is a method used to bind together multiple sheets of paper or other materials using a metal fastener called a staple. The staple is typically made of steel and is shaped like a small U. When a stapler is pressed down, the staple is pushed through the sheets and then bent over to secure them in place. This technique is commonly used in offices, schools, and homes for organizing documents. Stapling is quick and efficient, making it a popular choice for keeping papers together. It is also used in various industries, including publishing and manufacturing, for assembling materials.
