This week I saw a great deal on some blades I like (Derby Premium) on Amazon. When they came, the packaging was different from my last purchase. I was concerned they may be fakes, but some quick googling led me to some threads about the packaging changes and when I used one this morning it was a great shave. That led me to wonder if anyone was keeping a list of proven counterfeits we should watch out for when making a purchase? Some of those I've seen discussed and pretty much confirmed that fakes are out there are PolSilver, Astra, and anything Gillette. I found debate on if someone bought counterfeit Bic blades or if it was just the horrible quality control at Bic. It would be nice to have a compiled list in a wiki.
