It is always easy to break things, but hard to come up with something constructive. However, the approach of mankind has always been towards making something new or build up broken things, and this has often led to multiple innovations. Similarly, a simple attempt to join two broken pieces of wood with the help of a metal pin led to the birth of the nails. Since then, these nails have been used as one of the most common items that have the tag of fasteners for itself. However, one must not forget that the history of using nails is not very recent. Instead, they hold a thousand years of history and right from having general application to specific use in making household furniture, the nails have never failed to show their usability.
People are quite aware of the evolution of hammer, same goes the story for nails as well. Today there are copper nails, aluminum nails, and even rust free nails available in the market so that they can be used under all conditions and under all circumstances. The nails generally work in driving apart the fiber of the woods which needs to be broken. The fibers in the wood have got an elasticity inherent their characteristics, and that allows them to spring back again in place when the hammer strikes once. As a result of this, they find a solid grip over the nails immediately and allows the nails to serve their purpose.
At the stage of inception, nails were mainly shaped or forged with the hammers, and it was mainly the task of the blacksmith to bring them in shape one by one. The square iron rod was the tool that was mainly used for this shaping purpose. Once the rod is being heated in the forge, the blacksmith had to hit it on all the four sides which have been softened with heat and form a point. Once the shaft is being shaped up, the nails were then being put into the heading tool and hence the heads were given its due shape with the blows of hammers.
While the historic dates have the usability of the copper nails recorded, the current-day scenario has changed. Nowadays the nails are much stronger and since they are being built out of machines, they hardly have any deformities in shape, and hence the precision involved in the manufacturing process is much more than the ones used in the 18th or 19th century. Today copper nails have gained the prominence as they have proved the test of time and the inherent strength is much more than that of the normal iron nails.
One major advantage of using the copper nails is the lack of any worries for rust formation. Be it the roofs that you want the nails to work on or the wooden furniture that needs to hold itself stronger, the functionality of the copper nails have never failed. There have to be some added advantages for which copper nails are being preferred over the others and identifying them makes the difference.
