Rhinocerous/Horse/Gnu, its a mix of different hairs for leaded windows, used mainly on first cleans and when a rain guarantee is likely to be useful, or if your custards have a tendency to come out with 'Oh, can you leave them today please?'
One is flocked, the Gnu I seem to remember, one splays better with hot water, the rhino; and the other, horse, is shorter so useful in a dual-trim sense.
Some people swear by them, Ewan does, I cant see the point, all a load of old baloney Im sure
