Yes, you can! But that doesn’t mean you should. Quartz is naturally resistant to scratches, but if your knife is especially sharp, it can leave a scratch. In general, quartz can handle light cutting. However, there are more considerations necessary that go into the decision. Cutting on the hard surface of a quartz countertop will dull your knives over time. The other thing you don’t necessarily want is the contact of acidic food remnants with the quartz. While it won’t immediately harm your countertops, a quality quartz countertop will keep its shine best if you use a cutting board to protect it.
