Has anyone ever found this? I loaded an injector blade from a new pack of Chinese Schicks in my E Schick Injector and it was a dud blade. It was very dull and it shaved very badly - it seemed like part of it was dull and it pulled horribly. After one or two strokes, I switched to another razor. Afterward, I reloaded the razor from the same pack and the next day's shave was fine.
