Very few people in the world will be aware of this feature of stapler

There are two different pin shapes on the part of the stapler that holds the paper

 

We use many mechanical devices in our daily routine but these devices have some settings which common users never know about. Today we will talk about one such tool and that is the stapler. Did you know that the pins we staple are stapled in 3 different ways?
A stapler has two different pin shapes on the top of the paper. Most people know the same and don't pay attention to the other shape, the other shape you can change by rotating or sliding some staples. Thus the tips of the pin that will be stapled to the paper will be bent in opposite directions instead of bent inward. The purpose of this is to staple the pins so that you can remove them later.
Another method is to staple to softboards on the wall. For this, you staple the paper on the softboard on top of the stapler. Note that the lower level of the stapler has nothing to do with this.
