I am going to use my brand new Merkur 42C closed comb safety razor for the first time tonight. I have a blade sampler pack; so, I have not decided which blade I will use with it. I have used Shark razors, SE, with Dovo Shavette. Now I have only used my shavette twice, and this is going to be my first safety razor shave. I apologize if I did not use the search feature properly, but is there any advice I should take to heart before shaving tonight? I was thinking of starting with the feather DE blades.
