For a long time I used Derby blades, but then I decided that they were not sharp enough so I switched to Personna reds. Once again I decided that they were not sharp enough, so I have been using Swedish Gillettes for the past couple months. Now it seems that they have been discontinued, and I was never thrilled with the price. My question is where do I go from here? Are Feathers my only remaining option? I tried a 7 o'clock yellow, but it seemed pretty rough. Is that normal or did I just get a bad blade?
