Feathers, along with Personna Med Preps, and Gillette 7 O'clock Yellows, are all super sharp blades that deserve respect. If your lather isn't slick enough, your blade and is off, or you use too much pressure, you will get bitten. I've only Palm stripped these when I get to the higher number of shaves, sometimes 15, sometimes 30. Just to extend the blade life, for fun. I love them all extremely sharp blades, because any tugging from a dull blade hurts my face. I'm sensitive!!!!! Don't judge me. For Vintage blades, the sharpest I have found are the Wilkinson Sword Super Sword, Gillette Spoilers, and Personna 74(still testing one out).
