Super Badger, a concept that only appears in UK brands, is the category Silvertip refers to.
Finest Badger, mostly in the UK, is an older name for a class of 2-Band Badger hair (but does not include pigbadger origin), which is the side hair of the Badger. However, as the 2-band concept was not popular at that time, Finest at that time did not use the method of cutting off the white part of the base, but could only see the black and brown part in the middle. Finest is basically equal to its brand's 2-band right now.
