I now have a collection of razors to choose from, with only 2 or 3 being used on a regular basis. Is there any harm in keeping the blade in a razor not being actively used, or should such a blade be removed. Assuming the blade is stainless steel, no corrosion damage should occur, but I'm not certain regarding this. If such a blade is removed and set aside, how long is its shelf-life if it has been used once or twice?
