Having recently got into straight shaving myself I agree this is the best video , literally do what he advices for new guys and just do that one part of your face.
I started wet shaving using a straight razor then tried shavettes.. My friends let me borrow their razors and shavettes so I can try which ones I will be comfortable with, then I decided to buy the ones that worked for me..
The dovo can offer long and short blades, the short are a half of a DE and the longer ones are bought separately, the dovo comes with both blade carriers, I have one for sale if you are interested, the dovo is feather light, and the parker stainless has more heft to it but only uses the shorter blades.
