Astra Superior Stainless Double Edge Blades - 100 Blades 100 Blades (20 packs of 5 blades) Astra Superior Platinum Double Edge Razor Blades are known for their smoothness, sharpness and durability. These excellent platinum plated stainless steel blades are made by Gillette at their European plant in St. Petersburg Russia. This pack contains 5 blades, and each blade is individually wrapped to assure safety, sterility and long shelf life. Widely used by barbers in Europe, Astra blades can be snapped in half for use in a straight razor that takes a replaceable blade. They also fit all traditional double edge safety razors such as Merkur, Edwin Jagger, Muhle etc. This is one of the sharpest blades on the market - almost as sharp as blades that are nearly four times the cost such as the Feather. But the choice of blades is very personal. If you prefer an aggressive blade, then the Astra would be a very good choice. However, if you prefer a more forgiving, slightly duller blade, then you may want to consider the Derby, Dorco or Shark blades. Why We Like ItThese blades are an economical choice providing outstanding value and performance for use in your straight razors for the traditional wet shaving service, lining, neck clean ups and hair texturizing/finishing.
