My go to blade these days is the GSB. As I read through this entire post, I was surprised in the older posts from 2009 and such, the Derby blades were a popular choice. Nowadays the Derbys are public enemy #1 on the shaving forums. What happened to them?
Polsilver SI Astra Sp Voskhod Ladas Rapira Platinum Lux Nacet All give great shaves with my Merkur 34c. Trying the same blades in my recently acquired Fatboy G1 - so far they all work great with the Fatboy as well.
Astra Superior Platinum Gillette Silver Blue Kai Stainless Steel Perma-Sharp Super Polsilver Super Iridium Vintage Polsilver Stainless Voskhod Wilkinson Sword (German)
Not a bad idea..... It certainly would help in getting the general consensus on blade popularity and usage.
Fantastic shave tonight with my Astra SP. I believe the Astra SP gets better with age. I'm on my 5th shave with this blade and it is just as sharp and actually a little smoother than the first day I put it in. Love these blades.
I mostly just use family dollar 10 for $1 blades in all my DE's. I think they are ASR. Great shaves cheap and local.
