Hello everyone, I am completely new to straight razor shaving, before getting my first straight razor, I do have a couple of questions which I couldn't get answers online and wish the experienced shavers here would be kind enough to help me out.

I did a little search on the net about the advantages of straight razor shaving, some article said disposable blades pull up whiskers a little before cut, thus cause skin irritation, razor burn, redness and so on, why is it so? Does the same apply to DE blades used on a safety razor, or even on a Dovo Shavette?

I use both cartridge and safety razor to shave, and now hoping to get a Dovo straight razor. I just wonder how people grade these razors. Really wish to know so that I can decide which model I want to try. I am not talking about fancy features like gold plated ones, or luxurious horn handles, or super vintage ones with historical significance, but only for the sake of a quality shave.

And it's been like a myth to me that many say straight razors manufactured some years ago perform better than those produced today, even they came from the same brand. I wonder what makes the difference. The materials has changed? The way they forge them changed?

Seems I have asked a lot of questions, thanks for your time reading them.
