So confirmation on the Synthetic knot its going to be a FS G4.I have a few titanium things, but not brush handles.
In contrast to my recent burst of razor purchases, I haven't bought a brush since I don't know when.
However, I would certainly be interested in a Ti barbershop-handled 26mm brush, at a reasonable price. I've switched over to synthetic knots, so that would my choice.
I don't "do" FB or other social media, and am thus unable to comment there, but I like the idea. Thanks for raising it.
