I just shaved this morning with my Joh. Engstrom 6/8 Frameback, #14 in my 22 day rotation. I usually describe a shave in singing voices terms. To me a frameback shave is like being whispered to, almost inaudible. You have to listen to it very carefully to hear what it is doing. In contrast,a full hollow is singing in a high soprano. It took me several shaves with the frameback before I could fully appreciate the kind of shave I was getting. I almost traded it away but an extra shave with it convinced me that it is a good member of a very diverse rotation.
