why can you staple two ways
In addition to joining paper sheets together, staplers can also be used in a surgical setting to join tissue together with surgical staples to close a surgical wound (much in the same way as sutures). Typically, most staplers are used to join multiple sheets of paper.Paper staplers come in two distinct types: manual and electric. Manual staplers are normally hand-held, although models that are used while set on a desk or other surface are not uncommon.heir primary operating function is to join large numbers of paper sheets together in rapid succession. Some electric staplers can join up to 20 sheets at a time. A staple gun is usually a heavier duty, hand-held device; it can be strictly manual or pneumatic. Typical staplers are a third-class lever.
