I've been too cheap to pick up one of those solid clear brushes/handles off of eBay. I've had my eye on them for years, never wanting to spend more than 20 or so on them. I finally found one in the wild for $14 and it is in nearly perfect condition. The knot was a pork bristle that was so brittle it would drop hairs just from a simple pass of the hand. Its an Ever-Ready 934L. I was lucky and the same brittleness of the bristles was present on the old gluey crud the knot was held in with so with almost no cussin', it popped out pretty easily and without any drilling. I ordered a pretty little 20 mm black bristle with white tips synthetic knot from Shaveforge (no affiliation) on Amazon. I've gotten away from the bigger knots these last few years. 24 is huge to me, 20 is about just right. I repainted the inside of the knot cup and epoxied the knot in. I think it looks great!
