I know they are banned in a lot of places. Do any barbers use them anymore, or do they all use the modern disposable blade straight razor?
I think that barbars would be willing but that the local and state health codes will not allow it. My guess is that they'd have to use disposable gear because cleaning the blade after use is out of bounds.
Be careful about the guys who use the disposable blades. I have seen this happen with me more than once where they don't change the blade after each customer and give each new customer a fresh blade. I am talking about just where they use it on the neck and around the sideburns.
I always make sure I see them put a fresh blade in before they come at me.
