Full disclosure. Both of these reviews by Jason Rudman are NOT paid reviews. He was not provided special treatment or promised a quid pro quo for the reviews. They are organic and honest. He purchased one of these brushes when his name came up at normal cost and also was lent two other brushes for which he graciously auctioned off for charities. Also note, I no longer have the original Black Wolf hybrid fan knot that Jason compares this knot to.
