I have noticed that if a large bristle has grown, it is better to take a wide full or almost wedge from Sheffield: it is easier to cope. But in the problem areas they are not as convenient to shave. But this is a narrow razor copes. Let us assume that you have clarified this question for me. I'm still waiting for answers to other questions: the time of manufacture of the razor (at least before 1900 or after), and the material scales. And one more question: is Wheatley Brothers high, medium or low?
