I've got a new to me, one test palm lather, Omega Essential 10th anniversary boar brush. It is very usable in it's un broken in state, so my plan is just to shave it into shape and enjoy the transition. I have a well broken in Omega 10104 , five years plus starting at already broken in, that shows almost zero split ends, yet has extremely soft tips that are almost all tapered to fine points. I posit that after the boar bristles split, that the weaker side of the split eventually breaks off leaving a tapered end to the bristle. Time will tell but I'm having fun watching the bristle ends change over time and use. I already see more split ends after the first shave.
