Even stainless steel knives can be sharpened with a whetstone if their sharpness deteriorates. With proper maintenance, the sharp cutting edge can be restored. To remove rust from a kitchen knife, I recommend applying powdered cleanser to the blade and scrubbing it with a cork stopper or similar object. This is a medium-grit whetstone suitable for both stainless steel and carbon steel knives. It is also recommended as an introductory whetstone for those sharpening knives for the first time. When tomatoes no longer cut smoothly or cuts tend to stick together, it's a sign that it's time to sharpen.
