I don't know if Lord sells one blade in multiple packaging or what , but I have tried them all (Crown, Big Ben, Racer, Stainless, Super Stainless Blue/White, Super Stainless Green/White, etc.). I thought the "Platinum Class" would be different maybe. I was disappointed yet again. Lord blades just do not hold up to multiple shaves! This blade is loud, rough feeling, and dulls almost immediately. The typical three pass shave is just ok as a result, but the five o'clock shadow starts at about 3 o'clock so it is not a long-lasting close shave really. This combined with the fact that this is a two shave blade maximum is not acceptable for a "platinum class" blade. I believe Lord is really only selling one or two stainless steel blades with different packaging to match the marketing scheme. I mean, how could one company in Alexandria Egypt possibly make ten+ different blades. It's just not possible. I still prefer the Personna Blue at half the cost.
