For a chef's knife that is particularly lightweight and highly maneuverable, try the Shun Classic 6-in. Chef's Knife.
Like all chef's knives, it is an all-purpose blade ideal for a wide variety of cutting tasks. While the 6-in. length is perfect for slicing and dicing small to medium-sized fruits, vegetables, and other foods, many cooks prefer this smaller size for its sheer nimbleness.
