All-Clad has been headquartered in Canonsburg, Pennsylvania since the 60s. They make a range of metal cookware and are fairly well regarded by most cooks. The brand has been sold twice so far, once to Pittsburgh Annealing Box Co in 1988 and one more time by the giant French conglomerate SEB. While All-Clad used to make a lot of its cookware in Pennsylvania, a lot of low to mid range pieces are now made in China.
