So, I have an older brush that had a worn out boar hair knot. So, I just attempted my 1st re-knot. A bit clumsy for the first time. A bit nervous because I like this handle and didn't want to ruin it. I already have a similar handled brush with a beautiful bloomed badger hair knot. So I decided to stay with the stiffer boar hair knot. I'm happy with my first try. After removing the old knot, harder than I thought, I epoxied in the new one. Looking forward to using it.
