I am just a little wary of the slant concept and design. I suspect it would not fit into my current development as a DE newbie. (TL;DR..they scare the xxxx out of me)
I got a RR German 37 pretty early in my wet shaving journey.
I have never cut myself with it. I have cut my lip with other razors.
The head does all the work - you just pull down like you do with a standard DE razor.
No need to fear a slant any more than a DE.
I have since replaced the RR German 37 with a vintage Hoffritz that's basically the same design.
Both are EXCELLENT at cutting through multiple days growth and remaining a smooth, comfortable shave.
