What is the use of paper clips?

In the office, the most common use of paper clips is to clip files, put papers and folders together, and play a fixed role. In the training of "creativity", I believe that everyone's first reaction will be to say folder files, and then after a little thinking, they will say more uses:

String together like a chain; Make toothpicks; Bind things; Fork food; Stab people; Change the key to unlock; Grind into a hook to go fishing; If the button falls off, you can hook it up with a paper clip; Grinding can replace needles; Make curtains; Tattoos; Clip hair; Trimming flowers; Dip in ink to write;

However, paper clips have many shortcomings, such as uniform appearance, easy to rust in wet environment, single function and so on. At this time, plastic-coated paper clips have solved this problem well.

Manufacturing history

William Middlebrook, an engineer in Fort Worth, Connecticut, solved the problem of machine building. He invented a machine for bending wire paper clips in 1899. Middlebrook may also provide solutions to other problems.

Because the paper clip made by his machine has double loops, which is very similar to the paper clip we use. These paper clips are famous "Gem" brand paper clips. They usually don't damage paper. Paper clips are made of plastic coated with different colors.

This not only makes paper clips more attractive, but also allows users to "code" pages with paper clips of different colors. It seems that no one mentioned the patent of "Gemstone" brand paper clip, so it is impossible to determine who is its inventor. But since it was adopted at the beginning of this century, it has become a standard design.
