Here we go with the next comparison older vs new 2017 PPI blades. Both are PPI. Astra Superior Stainless. Old double wrapped packaging. Has been bought July 2012 (left). On the right is a new pack stating 10/20 and has ©2017. Laser etched inscriptions on the blade.
This one took me quite some time. Only brand new blades are compared in the same razor on two consecutive days. With that razor the brush, cream and even aftershave stay the same. I actually needed to try 6 blades in 3 razors just to be absolutely sure. I don't want to tell you unreliable conclusions. The razors used were Pearl SSH-02S OC, The Shave Factory adjustable and finally Ikon Shavecraft Short Comb (2 shaves with each respectively, only new blades).
These blades are not the same. Closeness of shave is the same, but the old double wrapped ones are a tad rougher and leave me with some light irritation for a few hours. Those who don't have very sensitive skin might not notice a difference, especially since closeness of shaving and sharpness are the same. But then again, there are people on the board who will not find a difference between a Feather and a Dorco.
Since closeness is the same, my preference is clearly for the new ones. But we are now waiting for the Indian made ones, right?
P.S. The old Czechoslovakian made Astra Superior Stainless are even rougher than the 2012 blades.
