Damascus steel knives can be prone to oxidation and lead to rusting. However, this isn't only for Damascus steel. Damascus steel has a high carbon content, so it's more prone to oxidation. There is nothing to be afraid of, though. Basic care techniques like drying your knife after use, not washing it in the dishwasher, and applying food-grade mineral oil when storing are enough measures. Opt for a stainless steel version instead if these sound too much work for you, but note that the patterns won't be as noticeable.
