Astra SP have been the cat's meow of blades for me. In all my razors they produce close, irritation free smooth shaves. However recently in a 4:00AM rush to the airport I was left with major razor rash and stubble from a quick shave. Thinking it was just due to a half-asleep sloppy job by me, did not think much about. Then that night shaving before a formal dinner, I had another horrible shave with same razor (schick krona) and blade. Noticed some of the Proraso cream was not even coming off with the first pass. ***! Opened up the razor and notice the infamous Astra packaging wax had piled up and collected some whiskers and caused weird blade gaps. Cleaned off the wax and detritus, reassembled and shaves were then smooth and close. So I will be cleaning the wax off before loading Astras for now on.
