The ideal little (4" blade) knives for peeling an apple, slicing a tomato, or cutting some cheese are made with Japanese high-carbon stainless-steel blades that have a non-stick coating. They stay super-sharp, and have a handy plastic protective sheath that keeps them safe. The sheath makes Farmer's Market knives great for taking on a picnic or camping trip. The Red knife has a serrated edge that's ideal for piercing tomato skins.
