It can't be helped! They multiply when wet!
I agree with the above post that the silvertips from Whipped Dog are nice for the price, but not perfect. The first one I got (30mm) was a shedder which Larry replaced no questions asked. The second one is much better, but still commonly looses a couple hairs during use. But for the price point it's a nice knot otherwise and he's great to deal with.
I'm waiting on my Highmountain Silvertip to come from Yaqi's 11.11 sale. Looking forward to trying it.
