When did the staple appear?
The original stapler was quite complicated because it had many operating steps. Therefore, in 1894, Briggs improved the original stapler. In this process, firstly, the iron wire is broken and bent to make a series of U-shaped staples. (The early U-shaped staples were wrapped in paper, and then put into the stapler separately when used. It was not until the popularity of staplers in the 1920s that U-shaped nails were glued into long strips and put on the market. These nails can be put into a much simpler machine after improvement, and the machine can directly embed these nails into the paper, thus eliminating a manual procedure. This machine is the prototype of stapler in today's office and home.
