I have a Unicorn Horn travel brush I bought awhile ago. I finally got around to reknotting it with a Blankity Blanks 14mm premium knot a month or two ago. Sadly, it's not so "premium". I'd call it pure, and a prickly pure at that. Now I plan to cut that out and put a ground down 16mm TGN Finest (if I can grind it down enough, which I doubt) or a Wee Scot knot in there. So does Simpson sell the knots for less than the brush or am I stuck dropping $50 on the brush to butcher it for the knot if I go that route?
