Pin
A pin is a device, typically pointed, used for fastening objects or fabrics together. Pins can have the following sorts of body:
According to their function, pins can be made of metals (e.g. steel, copper, or brass), wood, or plastic.
Pins have been found at archaeological sites dating as early as the Paleolithic, made of bone and thorn, and at Neolithic, Celtic and Ancient Roman sites. Neolithic sites are rich in wooden pins, and are still common through Elizabethan times. Metal pins dating to the Bronze Age have been found in Asia, North Africa and Europe, like the hammer-headed pins from the kurgan burials in the northeastern Caucasus.
The development of the pin closely paralleled that of its perforated counterpart, the needle. Archaeological evidence suggests that curved sewing pins have been used for over four thousand years. Originally, these were fashioned out of iron and bone by the Sumerians and were used to hold clothes together. Later, pins were also used to hold pages of books together by threading the needle through their top corner.
Many later pins were made of brass, a relatively hard and ductile metal that became available during the Bronze Age. This development was followed by the use of steel which was much stronger but tended to rust when exposed to humid air. The development of inexpensive electroplating techniques allowed the steel to be plated with nickel. Nickel did not rust, but tended to flake off the steel in humid weather, again allowing it to rust. However, this took many months or even years to happen, and as nickel plated steel pins were usually used only temporarily to hold cloth in place prior to sewing, no further refinement has been considered necessary. However, some modern specialty pins are made out of rust-proof and very strong titanium.
A pinners guild was first established in London in 1356, spreading to other towns, but falling short of the quality produced by French pinmakers, discussed in the Art de l'épinglier (French: Art de l'épinglier, lit. 'Pin art') (1761) where Henri-Louis Duhamel du Monceau gives details about the division of labor used by French pinmakers:
There is nobody who is not surprised of the small price of pins; but we shall be even more surprised, when we know how many different operations, most of them very delicate, are mandatory to make a good pin.
