Tried so far: Persona Comfort Coated, Personna Red, 7 AM, Derby, Merkur, Tiger, Voskhod, Feather, Many more to try.
I used nothing but Personna Comfort Coated for 40 days to build up some skill. I need to try the blades I tried before that to get a better comparison. Fun thread.

Looking forward to your write up. Good idea.

As I said earlier, I only use vintage now, but Feathers wouldn't be in my kit under any circumstances. que sera sera

Astra

Permasharp supers. Many have come and gone, these still remain.

I'd definitely like to hear your thoughts when your experiment ends!

Love them Derbys, Astras, and Rapiras!

If I try each of my 3o or so different blades in each of my 20 or so different razors, for one week each, soon I will know which works best with each razor. Hmmm. Daunting. I think I need more blades.

Yes you do, when I get my Derbys I think I am at the 500 mark

Crystal

Favorite razor blade? I have no bloody idea

500 is a good start indeed.

Chose "Other" My fav is Gillette Silver Blue

Bic

Whenever I get frustrated with my novice abilities, I grab a Wilkinson Sword and my confidence is restored. Not ready to declare them my "favorite" but they're becoming my go-to blade. Still have a lot more to try.

Voskhods, in a ball-end Tech

Just finished a week with a Personna Lab blue. Even abusively chasing the baby I couldn't get a bad shave- no irritation or cuts all week. By day 7 it was getting a bit dull though (the blade, not my shave). My only problem now is choosing tomorrow's blade for my next comparison. Derby? Astra? Crystal?
