So I was one of the lucky ones who received a brush from Graydog. And I chose the 26mm 70/30 badger/boar knot from Maggard's to go into the handle. This is my opinion on the knot, I have used it now I think 10 shaves in a row.
First off the when first doing test lathers with the knot it is dirty. Noticeable discoloration of water and soap on initial use. So I did about 3 test lathers where you lather and let the lather sit for a couple hours. It got better with this approach but it wasn't enough. So I took a little bit of Dawn dish soap and about a teaspoon of oxiclean and lathered that and let it sit. Finally it no longer smelled dirty and didn't discolor water or lather. The other thing I noticed right off the bat about this knot and it seems to be a common problem with those I have talked to, is that they shed. Not excessively but each shave I have lost hairs. Started around 8-10, and now I am down to about 2-3. The knot is jam packed so I am not concerned about it, but something to keep in mind with this knot. Some really hate when a knot sheds at all. If you are one of those I would avoid this knot. I do expect it to stop eventually.
Anyone else have any thoughts on these knots? Aside from the extra cleaning these might become my go-to budget friendly knot that is not synthetic.
