I was wondering if they are crappy blades or just me. The merkur blade I used for 2 shaves because I felt at the end of the second shave it was tugging a bit more. I then used a Wilkinson sword for two shaves and it was about the same as the merkur. But the shark was not a very good shave compared to those two. I am going to try to keep a log of how the blades do for me. So far I have a few categories.

Blade used.

Type of passes preformed.

Shaving soap used. It may affect performance it may not.

How the shave feels.

How my face feels immediately afterwards. I think I will add how my face fees through the day but usually after an hour or so my face kinda normalizes no matter what I do to it.

Dose the blade need to be broken in. I'm not sure this is really necessary because after 2 3 shaves it will go in the trash responsibly.

How long the blade lasts.

I am open to suggestions on what to look out for in selecting the right blade.
