Just taken delivery of 50 of these blades from Connaught, I had never used before so maybe a somewhat rash decision given the mixed reviews, as always opinions are as varied as the individuals reviewing. I use an EJ DE86 and have tried various blades with mixed results, most recently Feather have been my blade of choice. I am currently using Truefitt No.10 shave cream for reference. The Bolzano blades come in a simple cardboard box in packs of 5, they are meant to be an Italian brand although it states on the box they are made in Germany. I had two days growth on the face at first shave (I have quite a dark heavy stubble so this was a good test) and pleasingly the first shave was very comfortable and I would suggest as close as the Feather, I had achieved a nice smooth shave on 2 passes with no scrapes or tugs and no irritation, I have used the same blade now for three days and so far have not felt the need to change which suggests longevity may be superior to the Feathers which I would always change after three shaves. So far so good, I would score 8/10 sharpness, 8/10 for longevity, 8/10 smoothness.
