So I have my grandfathers old matching granite shave set (brush, mug, and stand). Its actually quite a beautiful set and something I remember from when I was little. My question for you gentlemen is if there is any way I can get the old boar bristles out of it and replace them with badger bristles. I have a pure badger brush but I cant stand it at all. Its to floppy and scratchy on my face and most importantly it doesnt match the rest of the set. I wouldn't mind leaving the boar bristle in because it is very soft on my face and I like the springiness I guess you would say backbone but its getting really brittle and I'll notice that their are individual bristles left on my face after I lather. If I had to guess an age for the brush I would say anywhere from 20-30 years if not older so I think it would be time to replace the bristles.
