Prototype single-ring 3XXL filled with 30mm Select Badgers we needed to evaluate. The handle was turned from what was a really ratty-looking piece of horn resin that had been sitting around the shop for months. Now part of my regular rotation.
Today was an Omega 21139 Boar a.k.a. "The Shower Hog". The knot is a little floppy. I like to use it with my Wilton Bicentennial pewter mug put out by Williams Mug soap in 1976. It's a good mug brush since it's made of rubber, no clanking on the sides of the mug. Just an occasional dull thud.
