Interesting to see this thread. I know that Astras have a lot of love on B&B but they have never been in my top tier of blades. I don't find them as sharp or smooth as many other blades.
The old ones were stamped and the new ones are supposed to be etched...that was the supposition on several threads, never saw an official confirmation anywhere though (but perhaps I just missed it).
geofatboy has a YouTube video about this from back May. All Astra blades are no longer printed on with ink, all blades are laser etched on one side with the Astra logo and the sides are no longer numbered. Laser etching makes counterfeiting much harder, I guess there were some reports of counterfeit Astra's showing up on the market in the past.
Thank-you for that. All I had heard till now were suppositions.
The guy seems like a trusted vendor, so probably didn't pull the info out of thin air.
here is the video:
