Shopping online to replenish my supply of Gillette 7 O'clock Permasharps, I came across some blades called Rapiras. Two types, the Rapira Platinum Lux, and the Rapira Swedish Supersteel. I'm just wondering if anyone has any experience with them. They are quite pricey, even on Shavebuck which usually has great prices on blades. They're Russian made, and I ordered some of the Swedes, but wondered if I was maybe wasting my time with these. Maybe they're great too. Just curious.
