Does anyone sells knots other then tgn and also im gonna make my own brush out of a very nice piece of african black wood for like $35 then get a 30mm Silvertip Grade A for $45 so thats like $80 total but how does the tgn knot compare to a duke 2 or 3 in best badger or a semogue 730 hd silvertip or owners club. Is it better to buy a name brush or make one.
