Cook´s knife / Santoku knife
The cook´s knife is also called Santoku knife from the Japanese kitchen. It works as an all around knife with many uses. With it's wider and rounded shape it's well suited to cut vegetables and also resembles the vegetable knife. A little bit smaller and lighter than the Master knife, some prefer it for finer slicing, dicing and mincing.
For people not cooking very often, the choice lies between the cook´s knife and the Master knife. Both can handle the generic cooking, though not specialized for any specific task.
