I got a Merkur blade with my first DE razor. Not knowing any better, I thought it gave a fine shave. I soon tried Derbys, which were awful, and thought even more of the Merkur blade, despite many negative reviews here. Shortly after, though, I found Astra SPs and settled on them as my regular blade. I bought a few hundred and have been happy for nearly 5 years.
About a month ago, I was PIFd some Merkur blades along with a Gillette Old Type purchase. I put a Merkur in my 34C last week, and the blade was pretty awful - tugging, whiskers left uncut. So, I'm either of the opinion that all Merkurs are bad and I didn't know any better 5 years ago or, as I've seen suggested here before, that Merkur supplies a higher grade blade with their razors than they sell separately.
