7 DEADLY SINS

• 
  
  Lust, someone who uses millions of safety pins as fashion accessory
  
  Gluttony, someone so hungry that eat safety pins
  
  Greed, the one who wants all the safety pins to himself because its a usefull object and want it only for himself
  
  Sloth, someone who never could use a safety pin because its to "hard.working" to open it

  Pride, pride of having the most beutiful safety pin in the world, covered in gold with diamonds and sapphires.

HOW IT WORKS?

This object is as simple as effective and maybe that's why earlier in 1300 or 1250 b.C. in ancient Greece and Rome, were used very similar objects called "Fibula" for various utility functions.

Is normally one piece of metal with two parts very fine and long that in one of the extremities is folded with two turns, causing a spring effect and at the other end has a slot in which a pointed part fits.  This slot serves two purposes: to form a closed loop thereby properly fastening the pin to whatever it is applied to, and to cover the end of the pin to protect the user from the sharp point.                 

 

The safety pin runs through the elastic capacity of the material it is made​​, typically metal, utilizing a spring effect that allows one end peaked has space to engage and disengage so that when closed it remains so without the loose risk.

With a material that does not have enough elasticity is not possible that this object works, it is indispensable that there is a movement of the pointed end so as to open and close.

SAFETY?

Safety pin, but this is actually an safe object? Yes, it is, however is possible to hurt ourselves using it, it wouldn't be the first time that someone was sting at the sharp end of a safety pin, this isn't the purpose of this object, is exactly the opposite, prevent someone to hurt himself at its sharpened tip, this tip can not cease to exist, cause without it, this object loses all its usefulness, and because of that, its was created the mortise of the safety pin, so that made ​​it almost impossible to open it without an intentional gesture, but when opened requires careful.. Nowadays pins are used with double security, the traditional mortise and a second closure that slides to lock any possibility to open unintentionally.

Many and many times, safety pins are used as fashion acessorys, they are versatile and allow thousands of different combinations to the limits of imagination.

IS USED FOR?

From the iron age in which they began to create the ancestors of the this thing, its useful has not changed that much. Its first use was to hold apparel or clothes in ancient civilizations that had no zippers. However this object can be used for other tasks like holding diapers, connect the most diverse objects, to fix or hold something or even just as a fashion accessory, which makes him a versatile stuff.
 

Colours

IN THE FUTURE

It is impossible to predict how this object will develop in the future. The shape is likely to hold the same mechanism, using as the innovative part, for example, different technological applications. However, due to the simplicity and efficiency of this object, it allows major developments in the mechanical aspect. As can be seen from his earliest "ancestors" of thousands of years ago, its shape does not change much. Probably can be replaced by any other objects with the same function not involving sharp tip.

Variations

VARIATIONS
There are thousands of variations of pins. These variations differ from one another or in its shape or its usefulness.
Since the first establishment of a pin, that there are different ways for the same purpose. Some major concern with the safety aspect, others facing the fashion aspect. Even with large differences all share the same mechanism, because it is the part that makes the object function and can be used. Then I leave you the most interesting examples I found in my research.
