Alternatively, Victorinox makes a serrated utility knife. It's basically a mini bread knife. The downside is they are super useful, so you may want it available for things other than cheese. The other option is to not worry about her using it for cheese. I'm a kitchen knife guy so I get wanting your knives to be taken care of, but as long as she's using it with a cutting board it's not like cheese is going to damage it or even make it need to be sharpened. What's the harm in her using it for cheese?
