Just finished a week with the CVS Single Edge blade. Although I wiped it off each day, that thing was quite rusty by the end of the week. Considering the risk of cuts by handling the blade each day, and the apparent ineffectiveness of wiping it off, I'm thinking I won't even bother trying to dry the next CVS SE blade I use. But, I'm wondering about that rust if I cut myself. The blade shaved well other than that.
