Ontario 7000 Old Hickory 72-6 Household Boning Knife. Ontario Knife has been manufacturing "Old Hickory" kitchen knives for over 100 years - in fact since 1889. The "Old Hickory" knives have stood the test of time and proved themselves as the best carbon steel kitchen knife sold today. Each "Old Hickory" knife is made with 1095 carbon steel, fully heat treated and tempered to provide a razor sharp cutting edge which is easily sharpened when needed. The knives are fitted with an attractive hardwood handle branded "Old Hickory" and secured with brass compression rivets. Caution, high carbon steel will rust if not properly cared for. Clean and oil after use, and keep out of the dishwasher.
