Shun Classic gift sets and block sets include combination's of the masterfully crafted knives from their Classic series. Each set is a great value. The Shun Classic Series is known for its exceptionally sharp blade edges. These edges don't require frequent sharpening like other knives. This is because the interior layer of each Classic Series knife from Shun is made from an exceptionally hard steel alloy. The outer layers keep the knife free from rust and breakage because they are made from a more flexible stainless steel alloy. This layered construction gives each knife's blade a unique Damascus finish. These knifes also feature Shun's beautiful PakkaWood handles.
