I recently purchased a few different knots types/grades from a few retailers ...The ones I have concerns about are labeled two band Shd...Under magnification I compared the hairs of High mountain, Silvertip and a cheapo black hair badger brush I have to the "two band shd"....To me the hair in the two band looked just like the black hair in my cheapo brush but with having the Tips Bleached to make it feel softer....If this is the case it seems a bit Shady to me...I could be wrong so please throw some knowledge at me...thanks
