I've been very impressed with what was an impulse buy...a Silksmoke knot brush from AP Shave Co off of Etsy.com. The brush is a bit softer than a tuxedo knot, it splays easily, but it still has sufficient backbone. It's the only one I have with that knot and I decided this evening to purchase a couple more. I bought the knots from AP Shave Co, but purchased handles from Shave Forge off of eBay. Came to approximately $22 a brush...very inexpensive for a brush that performs so well.
