The Original ChopStir was born from an aerospace engineer’s love for Mexican food and his quest for cooking utensils that would chop meat efficiently while it cooked. Now it’s a breeze to cook hamburger and other chopped meats! Safe for use in non-stick cookware, its patented scratch-free nylon blades easily cut foods into smaller, equally sized pieces, right in the pan, so it cooks evenly and in less time.
