The knot on that Duke looks lovely.
You’ve got a keen eye! Thank you. The original Best knot felt like a wire brush, but the D3 handle is fairly righteous! I used the brush every other shave for about a month, but it never improved. So I contacted the fabled gentleman brushmaker, Mr. Rudy Vey of New Jersey, USA. We exchanged one or two emails, and quite literally the brush made a full round trip in Under A Week. This was in 2015 or so. Despite the relatively short distance of perhaps 40 or so miles, USPS absolutely could not do that today. Truth be told, it was a marvel even then! The knot is by Shavemac and is a really delightful experience. If I had to keep only three brushes

this would be one of them.
