Does anyone know if there is a difference between Vintage Gillette Super Stainless blades and the one's marked "Spoiler"? Basically, did Gillette just add the "spoiler" moniker at some part for marketing and they are the same blade? I see some marked as only "Super Stainless" and others marked "Super Stainless Spoiler". Same, or different? This packaging: VS this packaging: Or even cooler, these from Argentina: So what is the consensus, are they all the same? Thanks!
