A sort of recent acquisition:
I've had the 404 for sometime but while I can understand why it gets recommended frequently it's not for me. I've had the 24mm Tuxedo knot since about September. Removing the knot proved challenging - steaming for 60 minutes had zero affect so it was drilled out and then just last week I had someone at work put it in a lathe and turn the opening to 26mm. I've hand-sanded it to a gentle chamfer so it's now 27mm. The knot is set to 54mm. I've only used it once but I'm very pleased with it. It'll become my travel brush I think.
