It should already ready "halved" Blades Being the breakup of Standard Blade has me so excited.
These blades are sharp and shave properly. Comparing to another I do not have it, but I'm satisfied.
I can not say what it looks like with edge retention and rust free, because I use a new blade for each shave.
For the modest price of 5 Euro for 100 piece that is also not a luxury that would a ruinous :-).
Naja- much more there really is not to be assessed in razor blades.
In my view, therefore, out around empfehlenswert- 5 Stars.
