Like I said, very sharp when first used, but second use is less than ideal. If I was one of you guys who use a new blade for every shave, I'd be thrilled with these. However, I'm kind of a cheapskate when it comes to shaving. I'll use a blade as long as it keeps cutting. I can force a Feather blade to last up maybe 5 shaves, but the 20 year old platinum-plated, tungsten-coated, hardened stainless-steel English blades that I'm trying to replace might last for 20. Another small thing, these blades are a tiny bit narrower than average, which causes me to adjust my old Gillette to its most aggressive setting on first use. I suppose this could be a cause of the short life of the edge. The Feather blades seem okay for the price, but I can't consider them premium quality.
