Razor Blades ClubDouble Edge Razor Blade Sample Pack (2x each)

What’s the best one?

How did you go about sampling, did you dive in, alphabetically or what you thought was smoothest to sharpest Thx.

Just received..is their a particular order to use? IE...Feather seems to be the sharpest and should try last.

I bought a Weishi butterfly razor off amazon for $16 that came with Weishi blades. Which of these is most similar to the weishi blades?
