Those of you who don’t like the idea of “unitasker” kitchen implements should look away now, because this knife was designed to cut only one thing: lettuce. These knives are made of plastic or nylon and have serrated blades. Supposedly, these materials are superior for cutting lettuce because they will make lettuce less likely to turn brown at the edges than metal knives.
Now, I have never had a problem with the metal blades of any of my knives turning lettuce brown. The only thing that does that is leaving the lettuce in the refrigerator a few days too long and, as I don’t make a habit of preparing my salads several days ahead of time, I think I’ll pass on this particular knife as a salad-making tool.
I would consider using it as a cake knife, though, since it would be much easier/safer to transport to picnics, parties and other events.
