The Reds are amazing and just bought 300 of them to ensure I can enjoy them for sometime to come. Not sure how they compare to the ones now made in Germany.
The Israeli "Crystal" blades are pretty mild forgiving blades that allow me to shave more aggressively. Our domestic Personna blades (blue) seem sharper than those made elsewhere IMO.
Thanks for the information! I can imagine that even blades made under the same brand can be different when made in different locations. I haven't heard of Crystal, I hope to give them a try!
