I don't really buy the whole, it's for shaping head hair not shaving faces thing.
If it shaves hair, people use it with good technique and get satisfactory results that they are happy with, why can't they.
The Dovo has the option of the longer Dovo blades, I can't see them blades being used for shaping hair... So surely they are designed for shaving faces?
I get really confused when people call an Artist Club a shavette, and deem a shavette suitable only for hair shaping. Feather call it a barbers razor, a barbering tool, barbers have to use disposable blades these days, that doesn't mean they're specific to hair shaping?!
For what it's worth I don't let barbers go near me with Shavettes any more, even for hair shaping, they use cheap rubbish, with Derby blades which I hate, and always cause me a tonne of razor burn
