My T-400 with the silvertip knots commissioned for our own @Vlasta may be the finest brush I've used. Certainly right up there with my favorites.
First shave with Jayaruh 304 Big Boar! This brush is absolutely the finest new boar I have ever had(I have about 15 I use regularly). The 30MM knot loaded Penhaligon's Sartorial very easily and whipped up a tremendous lather. The knot holds an insane amount of lather a gives it up very freely. There is no noticeable scritch to this knot(from Whipped Dog). There will be a very short break in period, I sure. Kudos Jim Roe!!!!!!!!!!! What a fine brush maker indeed!
