While granite countertops are generally very durable and resistant to scratching, it is not recommended to use them as a cutting board. Granite is a natural stone that can be quite hard, which means it can dull or damage your knives over time. Additionally, cutting directly on granite can also cause the surface to become scratched or chipped.
Using a cutting board is a better option as it protects both your knives and your countertops. There are various cutting board materials available, including wood, plastic, and bamboo, that are designed specifically for cutting tasks. These materials are gentler on your knives and provide a dedicated surface for cutting, minimizing the risk of damage to both your countertops and knives.
To keep your granite countertops in optimal condition, it's best to use cutting boards and avoid cutting or chopping directly on the surface. Regularly clean and seal your granite countertops as per the manufacturer's instructions to maintain their appearance and durability.
