Editing Hammerstone (section)

==== Spain ====
Until a few decades ago, in Spanish towns such as [[Cantalejo]] ([[Segovia]]), flint was carved for the manufacture of agricultural [[threshing]] machines. The flint carving technique was very simple and standardized, aimed at obtaining wide and short but resistant chips of about three centimeters. For this, different hammers were used. The hammer used in the final phase, that of the flake itself, was a long and narrow-handled wooden peg, with a small, almost tiny, metal head with two thin and prominent ends. The metal mass of this type of hammer is very small compared to its long and flexible handle, which, in addition to increasing the speed of the blow, combines the potential energy of the wooden handle with the hardness of the small metal pick. Thus, a direct hard percussion is obtained, with a soft, elastic impact.<ref>{{Cite journal|last1=Benito del Rey|first1=Luis|last2=Benito Álvarez|first2=José-Manuel|date=1994|title=La taille actuelle de la pierre à la manière préhistorique.
