I dont have the specific information about the type and material of Stone Honeycomb Panel used in your countertop. In general, Stone Honeycomb Panel is highly durable and scratch-resistant, and it is unlikely to get easily scratched by a knife. However, if the pressure is applied with excessive force or if the knife has a very sharp edge, it can potentially scratch the surface. To avoid any scratches or damages, it is always recommended to use a cutting board while using a knife on any countertop surface.
