The Old Hickory knife is made with fully heat treated and tempered 1095 carbon steel. Fitted with attractive hardwood handles secured with brass compression rivets. After assembly, these knives go through a sharpening process to guarantee a sharp edge to meet all needs. Old Hickory has stood the test of time and proved to be the best carbon steel kitchen cutlery sold today. Ontario’s 5-Piece Old Hickory Cutlery Set include the following knives: Old Hickory 4″ Paring Knife Old Hickory 7″ Butcher Knife Old Hickory 8″ Slicing Knife Old Hickory 6″ Boning Knife Old Hickory 3 1/4″ Paring Knife Carbon steel knives are preferred by those who want a sharp, long-lasting edge. With use, a carbon steel blade will develop a distinctive dark finish. This is not a defect, but a natural result of the use of high-carbon steel. Carbon steel blades are not dishwasher safe, never let them sit in water for a long time, but rather hand-wash and dry your knives to avoid rusting.
