Hi All Are these blades corroded? The Personna Med gets like this around the sixth shave (this is the second blade I have used and both had the same results). Only the Personna Med seems to do this to me (I haven't used a Lab yet). The Wilkinson Sword (made in Germany and in black pack) looked like this after the first shave. I will be trying another Wilkinson Sword. My normal clean up procedure is rinse in water, then shake off water and let soak in 99% alcohol (the Wilkinson Sword I let soak in olive oil last night before I used it today for my first shave so I have no idea if it looked like this before shaving with it today - it looked normal when I took it out of the wrapping yesterday). Thanks for your help.
