Hi all, I bought one of the collapsible chrome travel brushes from Edwin Jagger back when I first started wet shaving as I was traveling a lot. It served me well but I stopped traveling a few years back as I began taking care of sick parents. Fast forward to now and I just got back from my first trip in a while and I noticed the poor battered badger knot seems to finally have given up. I am now looking to replace the knot with a synthetic one as I think it may hold up better to the rigors of travel. From the product info I found the knot was 20mm with a 50mm loft. I have looked around but it seems the shortest 20mm I have found is 63mm. As I have never replaced a brush knot I don’t know if this will be too long. Has anyone replace the knot in this style of brush and if so could you point me in the right direction for buying a replacement knot? Like I said preferably synthetic but I am willing to use a badger as well.
