So in all my free time the past few weeks, I've managed to do some restoration work on a number of straight razors, cabinets, razor storage, etc. One thing I haven't done in a good long time is a shaving brush restore. So I snagged this little 'gem'—and I use this term loosely as this Rubberset is in need of some serious TLC. I suppose I just love a GOOD challenge! I'm not sure of the diameter of the knot & won't be certain until I have the old brush in hand. TGN boar? TGN badger? Hmmmm. Any helpful tips about these long-handled beauties you more-experienced brush men can throw my way would be greatly appreciated on such topics as knot-removal, knot types, adhesives.... It should be fun.
