I have noticed a number of pictures of Simpson - Trafalgar T3 brushes showing a “Donut hole” in the center of the knot. Most of those pictures are on the “ What did you use today” threads. I know this can happen when too much pressure is used when splaying the knot, but it seems to show up more on this brush than any other I have seen.
I’m curious if others have found this to more of a problem with this particular brush.
