Beautifully designed and engineered to hold up to the rigors of metal whisk, spoon and spatula use, the Calphalon Williams-Sonoma Elite Nonstick 13-in. Wok gives you the convenience of nonstick, the highest levels of performance, and more versatility than ever before. Now you can cook with the utensils you love − without damaging your non stick pans. Traditionally shaped with high, sloped sides, this stir-fry pan has a flat bottom for easy stir-frying on modern stovetops. Woks are shaped so foods can be seared on the bottom, then pushed up the sides to finish cooking.
