Question here for the group about two brushes that I own and want to alter. The first is an Art of Shaving brush I purchased something like 6 or 7 years ago. Was my first brush and is a pure badger. The loft is high, its floppy and just not the greatest quality; how would I go about removing the existing knot and then putting in a synthetic or some other that I purchase? The second question may be more difficult but hoping there is some wisdom here to make it possible. I have a whipped dog silvertip brush that I love but after having multiple brushes afterwards and using this one still in the rotation I've come to realize that I really would get more out of this and love it even more if I could sink it say 10mm or so as its become a little floppy for my liking. The brush is awesome and was created exactly as I requested. Is it possible to safely remove the knot without damaging it or the brush, drill the handle a little deeper and resink the knot? Thanks for the input everyone!!
