Ceramic knives will not corrode in harsh environments, are non-magnetic, and do not conduct electricity. Because of their resistance to strong acid and caustic substances, and their ability to retain a cutting edge longer than forged metal knives, ceramic knives are a much more suitable culinary tool for slicing boneless meat, vegetables and fruit. Also because of their non metal blade fruit and vegetables will not brown from oxidizing. They are hygienic and non-allergenic.
