I have just taken an uncontrollable urge to buy a brush. Can anyone explain the grading system which is used by Rooney? Also.....any hints on the knot size of a Style 1 Large. I want something approx 26mm.
A Rooney style 1 large has a knot diameter of 26 mm..
As for the grading system:
Rooney uses five different grades:
their pure and best are more or less like the best badger of other brands; their silvertip is of a very thin, fine, soft kind whereas their super is the best of their silvertip bundles of badger hair; finally, their finest is resembles the high mountain white of Plisson and the Manchurian badger of Simpsons, although that of Rooney has an extremely white color.
