I heard a representative of Smokey Mountain Knife Works telling a customer the other day " Carbon is softer and will dull faster but is easier to sharpen, a stainless blade is a little harder to sharpen but will maintain a cutting edge much longer". Carbon does need to be oiled more often as carbon steel is more prone to rust, but then again like another user that I agree with......

"As far as oiling, it depends upon local humidity. I don't think guys in Wyoming have as much to worry about as someone in southern Mississippi. Also, how often the razor is used is a consideration. I don't oil any of my razors that are in rotation."
