EXTREME NONSTICK: Engineered not to scratch, our nonstick has been laboratory tested to last 130x longer than the competition—that’s more than 350,000 scrapes without scratching. TAKE IT TO THE EDGE: 14-inch wok's thick, edge-to-edge steel base is induction suitable and delivers fast, even heat with enhanced, warp-resistant stability from stove to oven. NONSTICK INSIDE AND OUT: Crafted with durable aerospace-grade materials to create a thicker and harder surface than ordinary nonstick and eliminate scratching, sticking, and flaking with our most advanced nonstick yet. Your wok will look newer for longer with a stain-resistant, easy-to-clean nonstick on the interior cooking surface and exterior finish. TRULY DISHWASHER SAFE: Extreme ScratchDefense wok with lid from Circulon is truly dishwasher safe for convenient cleanup without sacrificing performance. SMOOTH HANDLING: Made from cast stainless steel and silicone, our handles provide a comfortable and secure grip to boost performance, balance, and handling in the kitchen.
