The glue was strong and black, hard to cut out. The shedding bristles were breaking off above the glue.
My last remaining 20mm boar knot was too wide in the glue bump department, but a 20mm badger slid in easily.
I restored one about ten years ago. Nice handles!
I set my badger knot a little lower than yours.
Probably. Mine's pretty low.I put a few millimeters of spacer below my knot. If I had set it at full depth I think mine would still have been slightly higher lofted than yours.
