I tried at least a dozen other blades. Feathers get the closest shave with the least irritation for me, by far. My beard is very coarse, so it really prefers a sharper blade. They’re also very consistent in their performance, for the first three shaves.
Wilkinson Sword and Gillette Silver Blue were runners up for me. I got many good shaves from them. But they lacked consistency in my experience.
Feathers are definitely not the blade for new wet shavers, though. The first time I used a Feather blade, I slashed myself up real good. I suggest using Gillette or Astra blades for a couple months before trying these.
Side note on that premium price. Keep in mind, 12 cents per shave is still a steal compared to cartridges.
