I'm going to be sending in my two vintage Gillette Slim adjustables to be cleaned at Razor Emporium. It's not worth it to send them in one at a time because it makes more sense to pay for them both at once. The problem is that will leave me with no razor. So I need something in the meantime and I figured why not get the Razorock Switch so that I can play with a shavette-style razor to sort of start to get a feel for the technique of a straight razor. And it's affordable. My question is how aggressive is the Switch in comparison to my Slim? What number would it correspond to? I currently shave on #1 and finish on #2. Will I find the Switch too different?
