I am new to the straight razor, but have been shaving for well over 50 years. I've been using a couple of old brushes from my dad and granddad, and although the both make lather, neither is in really good shape, or comfortable to my skin. I am not sure of the material, except they are NOT synthetic.

I am in the process of selecting a couple of new brushes, and have been reading as much as I can about the various options. I have decided that I will purchase a badger and a boar bristle brush in order to try them both. There is a plethora of information about the badger brushes and their grading, but I haven't been able to get my eye balls on anything about various grades of boar brushes. Can someone point me in the right direction?

Thanks in advance, Jack in Fiddletown
