Zenith Pro Aluminum Handle Big Boar Shave Brush. 26x57mm knot. B2
Metal Handle Professional Shave Brush. This brush has a large and dense 26 mm Boar Knot attached to it. Unlike most of the other Zenith Pro brushes, loft is set at only 57mm. Effective loft is 52-54mm from the glue bump. This makes this brush a great face latherer without the flop. Total weight is a respectable 92 grams.
In one picture, I've shown a used Omega 48 for comparison. It is very similar in size. While the actual knot height is shorter, the perceived knot height is even less because of how the Pandolfo artisans epoxy the knots. Finally, the Omega 48 is chromed plastic and the Zenith is aluminum. I also have a metal chromed version. Search for B19
