HI everyone. I've been shaving for about 10 years and have used 2 blades, 3 and even 5 blades. Right now I use an electric but I just ordered a new DE and badger brush from Edwin Jagger and am waiting for them to arrive. In the meantime however I have been reading about how these things can mess up your face if your not careful. Whats the worst thing that can happen? can they leave permanent scars? I've had nicks and cuts before but is there anything that I should really look out for when shaving with a double edge?
