Heavy-duty staplers are designed to handle larger stacks of paper than standard staplers. They typically have a stronger mechanism and can staple up to 100 sheets at once, making them ideal for binding reports, presentations, and other large documents. These staplers often use larger staples, which provide better holding power for thicker materials. Many heavy-duty staplers are built with durable materials to withstand frequent use in offices or schools. Some models feature ergonomic designs for comfortable handling, while others may include a built-in staple remover. Brands like Swingline and Bostitch are well-known for their reliable heavy-duty staplers.
