The first modern straight razor complete with decorated handles and hollow ground blades was constructed in Sheffield, in England, the centre of the cutlery industry, in the 18th and 19th centuries. Benjamin Huntsman produced the first superior hard steel grade, through a special crucible process, suitable for use as blade material in 1740, though it was first rejected in England. Huntsman's process was adopted by the French sometime later; albeit reluctantly at first because of nationalist sentiments. The English manufacturers were even more reluctant than the French to adopt the process and only did so after they saw its success in France. Sheffield steel, a highly polished steel, also known as Sheffield silver steel and famous for its deep gloss finish, is considered a superior quality steel and is still used to this day in France by such manufacturers as Thiers Issard.
