Rocker knives are specialized kitchen tools designed for cutting and chopping food with a rocking motion. They typically feature a curved blade that allows users to apply downward pressure while rocking the knife back and forth. This design makes it easier to chop herbs, vegetables, and other ingredients quickly and efficiently. These knives are often used in conjunction with a cutting board and can be particularly helpful for those with limited hand strength. Rocker knives come in various sizes and materials, including stainless steel and plastic, catering to different cooking needs and preferences.
