The Muhle syn is my travel brush and I have a Rudy Vey with the same knot.Jim, thanks. Yes, that's my favorite knot. My daily driver for going on five years is the Edwin Jagger XL version, but I wanted a curvier, prettier handle. I use almost nothing but these Mühle synthetic knots (my travel brush is the 23mm). Rudy did a great job on this handle. I wanted a cross between an Emillion and a curvy PJ, and this is it.
