The topic is fairly self-explanatory. What's your favorite blade and why? How long have you been using it, and how do others compare to your favorite? So far my ties for number-one favorite are the Gillette Bleue Extra and the Super Iridium/Iridium Super. Both give me close, smooth shaves with no or almost no nicking even in my problem areas of the neck and corners of my mouth, and no irritation. Runner-Up: Personna Lab Blue — Nice and sharp and practically no irritation, and made in the United States. Third Place: Astra Superior Platinum — Not as close as the others, but quite forgiving on my face. Compared to other blades I've tried, these were the ones that gave me the best shaves and least nicking and irritation. Others, such as the Treet Carbon Steel "Black Beauties", were good but tended to wear out sooner. My worst experiences were with the Van Der Hagen, Dorco Prime Platinum, and Feather blades. The latter two brands were super-sharp, perhaps too sharp for my skin type, leaving me nicked, irritated, or both.
