In 1923, James A. Chrestensen, who had been with Ontario Knife Company (OKC) for a dozen years, became president and the beginning of the "Old Hickory" line within OKC would begin. His son Robert F. Chrestensen would take over as president after his father retired in 1952. Please note that the Old Hickory knives are made with carbon steel. Carbon steel knives require extra care to prevent rusting and oxidation of the surface. We recommend cleaning the blade with a damp sponge or cloth and dry thoroughly. Some people go a step further and apply a light coating of vegetable oil to the blades surface. If your blade shows signs of rust, use some steel wool to remove it and then apply some oil to the blade.
