One standard whippeddog 24mm handle and the other was a cheep wooden 22mm. Bought a couple knots from China for cheep and installed them. The one that went in the whippeddog was a finest badge. Very soft. The one that went in the wooden handle was a Best Badge but over stuffed knot. I'll try to take pics after work. The over stuffed knot bloomed out like a muchroom! Nice backbone and huge on top. I might need to try and drop it down a bit more it i can get it out without damage but it sure works well now.
This removing and replacing knots is not a hard thing to do. I was going to toss the cheep wooden handled brush as it was just not worth using. But now i got a fine brush out of it.
Changed out to knots
