Bear in mind that "Pure Badger" is actually the very lowest grade of badger hair.
The main types, from lowest grade to highest:
Pure Badger
Coarser hair from the underbelly. The hair varies in softness, pliability and colour. Usually, the ends are trimmed to shape, resulting in rough stiff ends. Very cheap.
Best Badger
Finer and more pliable hairs. More densely filled with hair. Ends are usually trimmed to shape.
Super Badger
An excellent hair. More expensive than the lower grades. Better graded hairs and not as prickly. Fitted to the knot so that the ends do not have to be trimmed to shape.
Silvertip Badger
Superb quality. After the first use it flares out and becomes very fluffy. Holds a considerable amount of water, and makes a much better rich, creamier lather.
Extra Silvertip Badger
Simply the ultimate. Not always easy to obtain. Expensive. Holds an incredible amount of water.
