In 2008 Badger & Blade issued a Limited Edition that was made by Kent. The knot is far denser that the Kent norm and feels much like my Simpson AS4.Polo 8.
The BK 2 is the same size as the BK or BLK 4 but has a Pure Badger knot.
Kents modern Silvertip line is the BK or BLK 12, 8 & 6. BK handles are Ivory colored and BLK black.
Kents modern H series brushes have striped handles and Pure Badger knots. An H12 is on the left, a H8 on right.
This is an earlier Kent M6C with a Catalin handle.
Kent sold the V8 series from the 1960s through until the 1990s. This is a late V8, likely from the 1980s.
Kent also makes Boar and today even synthetic bristle brushes. This is an older wood handled VS80 boar. The current VS80 handles are a different shape.
A prior owner of this brush was told by Kent that it was made in 1923. For almost a hundred years it has been patiently waiting to get used for the first time and finally it will get it's chance to show why it was created.
Here is the whole family together so that you can see relative sizes.
