They don't make them like this anymore. These 12 year old blades are better than today's Personna equivalents. Either the design has changed, the material is different, or the manufacturing machines have worn out. Very sharp and smooth shaving DE blades.
I bought these for about $.07 each at auction. At that price it was a great deal. I don't know what the regular price is, or even if these were not NOS. They give a very good shave, but not as good for me (YFID), as Astras, Dorco Prime, or Wilkinson Sword Classic. I'm getting 3 shaves, shaving daily. Blades made in Israel. No indication of any coating. Are these "Israeli Reds"? I don't know.
