This 4-piece Laguiole Du Monde steak knives set is made from stainless steel. The 4.3 inch blade is made from stainless steel and is fully serrated. Thanks to the 0.7 thick blade the knives are very sturdy and sharp. The knives are suitable for all kinds of meat, fish, vegetables and fruits. Each set comes with a wooden storage block for easy access and safe storage. Although the knives are dishwasher safe (up to 130f), we recommend hand washing these items. Laguiole Du Monde Designer Line knives ensure high quality kitchen products for an affordable price.
