Well I got a chance to use my BB9 today. It's funny. The vintage bakelite (Cheap) Kent I bought has this wonderfully soft knot. This fancy schmancy Ivory travel brush has one of the prickliest Badger knots I've ever used. It must be that days version of "Pure" or even "Black" badger. It's disappointing, the knot is in decent shape and I might replace it just because I'm so unimpressed with it.
