I'm on a bit of a synthetic brush spree. I purchased the three knots offered by APSHAVE CO. And sunk them into whipped dog handles. I must say for all the well deserved talk about the tuxedo knot I think I like the cashmere the best. If you haven't already tried it you owe it to yourself to do so. The cashmere has tips as soft or softer than the tuxedo with less backbone, splays a little easier. The synthetic horse hair is no slouch eather.
