A popular legend and persistent, which probably dates back to over a hundred years ago, argues that the "old days", people drew knives from old cutting tools, files, files in English ecc.chiamati. The perpetuation of this myth has led many amateur forgers and to forge knives and razors from old files also having some success. Even an entrepreneur 's Illinois, in 1906, advertised his company, a manufacturer of butcher knives, as the "Old File Cutlery Company." That is, the contractor did a virtue of necessity', admitting Chei his knives were made with old Forged in Sheffield steel instruments. This company has continued its activities successfully for six decades, but most probably, in reality produced by the knives were made from new billets of steel.
The fact is that, so unquestioned, 1740 to 1907 the tools cutting steel Sheffield were considered the best in the world, especially those produced in Cast Steel. In America, in 'Ohio, Mississippi, on the Pacific Coast, local traders sold silver and steel products in Sheffield.
If a forger was too poor to buy a new steel bar, at the same price he could buy various scrap old Sheffield, then still an excellent steel, and get the knife.
In the century we live in the steel and the tools it rivacati are cheap, and has now established a culture of 'throwaway'. The old knives are not only not over 'reused to manufacture new ones, but also sometimes are not even the most' riaffilati.Prima advent of industrial-scale production of steel, the tools of high quality were obtained by means of an electric oven 's Héroult, introduced in 1907. However, the creation of cutting tools hand-forged continuous' tradition as in Sheffield, until 1960.
Following were automated, to obtain a better adjustment of the blades, tools for cold treatment.
Even with electric furnaces was possible a good control of the times and temperatures, including in relation to the various content in alloy steels, it was noticed that the Sheffield steel was too expensive to confound and restore without accumulating stress and tension within it, which would make it difficult to manufacture the tool below.

For me, once thought to find historical references on the forging of knives from old files around 1920, soon after the First World War, when the market was literally flooded with an unbelievable amount of explosive remnants of war. I was wrong. The first reference dates back to about 1935.
The magazine "Professional Industrial & Art " in the October issue of 1935 a reader wrote to a charge of drawing up wondering whether it was more 'expensive perte forge a knife from the bar of steel or made from an old scrap of technical response to the reader made clear that he was more 'expensive and more' difficult to produce a blade from an old files rather than derive it from a new billet.
In the December of 1939 the same magazine, was published an article showing how to make a knife in the north-western Indian style (curved blade) for working wood, from an old file.
