Staplers
A stapler is a mechanical device that joins pages of paper or similar material by driving a thin metal staple through the sheets and folding the ends. Staplers are widely used in government, business, offices, homes and schools. The word "stapler" can actually refer to a number of different devices of varying uses. A staple gun is usually a heavier duty, hand-held device; it can be strictly manual or pneumatic. Staple guns are used to fasten a thin material to a solid backing, such as a piece of paper to a bulletin board, or to a piece of wood. The two legs of a staple from a staple gun are not folded over, but are embedded straight into the backing material. Modern staplers continue to evolve and adapt to the changing habits of users. Less-effort, or easy-squeeze/use staplers, for example, make use of different leverage efficiencies to reduce the amount of force the user need apply. As a result, these staplers tend to be used in work environments where repetitive, large stapling jobs are routine. Large staples might be used with a hammer or staple gun for masonry, roofing, corrugated boxes and other heavy-duty uses. Smaller staples are used with a stapler to attach pieces of paper together, such staples are a more permanent and durable fastener for paper documents than the paper clip
