Have your read the 1961 barber manual excerpt on honing and stropping here in the SRP Wiki Help Files ? It addresses what they consider the proper edge profile and how to achieve it and keep it.

I'm not saying to turn it from a slight frown to a slight smile but using their method you ought to be able to get a neutral bevel, neither here nor there, and that is what many of them are nowadays.

Whatever I did it wouldn't be breadknifing. As slight as the frown is you ought to be able to work it out and not need any drastic measures that create more work than necessary.
