My only slight grumble is that the Astras do seem to dull quite quickly, so by the end of the week i can feel a bit of drag. I’m going to get me some of those Feathers and see if they make a difference,
Feathers are slightly sharper than Astras but dull quicker than Astras so I don’t think Feathers are your solution. I love feathers but save them for when I want a really really close shave and only use them for 2 or 3 shaves.
After trying quite a few blades, I think that the Astras are the best compromise between sharpness/smoothness/longevity, in a merkur 38c anyway. They are also currently one of the cheapest if you get from the guy on Ebay which is nice…
7o’clocks would be next on my list for you to try for longevity but only the black packet ones, not the green or yellows.
