I just starting using a vintage Kent KS8 today, which has a cased boar knot (core of boar surrounded by a very thin layer of badger). I am well aware that boar knots have a break in period where the ends split, and it takes a bunch of scrubbing to do it. Question is, what is the fastest way for me to make that happen, assuming I use the same brush once a day, every day until broken in. Will it happen best if I bowl lather or face lather?
