If you're first starting out with a safety razor, or looking for a new favorite blade, this sample pack is a great place to start! Feather: Stainless Gillette Silver Blue: Stainless Polsilver Super Iridium: Stainless Ladas: Stainless Rapira Swedish Supersteel: Stainless Derby Extra: Stainless Personna Super: Stainless SuperMax: Stainless Rapira: Stainless Voskhod: Stainless Astra Superior Platinum: Stainless Shark: Stainless Bolzano Superflex: Stainless Treet Dura Sharp: Carbon All new single blades, ranging from the super sharp Feather to the only carbon blade in the bunch, Treet (very sharp, just wipe dry after using to prevent rust). A fun addition to the bunch is the Bolzano Superflex, an Italian retro blade which hasn't been manufactured in decades. Note: The Polsilver isn't stamped with the brand, so I marked the blade to ensure identification.
