This is a Hammer Stahl 4qt Sauté Pan review, including both PROs and CONs, after using it in our kitchen for 2 weeks. Hammer Stahl is one of the oldest cookware companies in the North America, founded in 1874 in Sheboygan, Wisconsin. In the 1970’s, they began manufacturing their famous Hammer Stahl American Clad Cookware factory in Clarksville, Tennessee. Their team of American workers hand-crafts the 7-ply surgical steel cookware and German-steeled knives.
