I have now shaved 2 days in a row with a Gillette Nacet blade. Surprisingly nice. Initially I loaded it in my Progress. After one pass on the cheek, it did not feel right, and I switched it over to my 40's superspeed. Amazing difference. This turned out to be a moderately sharp blade, but with great smoothness. I have not been able to find them in bulk packs, which keeps me from stocking up. I will buy another 20 or so in 5 packs to keep them around for a change of pace. If you are buying from a vendor that has them a 5 pack may be an interesting experience.
