2 years ago, I bought a Vikan brush, a heavy brush when compared to gardiner brushes, so I took it round to a mate of mine who is a carpenter by trade. He has all sorts of weird and wonderful machinery in his workshop so I asked him to trim the stock down to bare minimum to reduce weight.
I still use that same brush to date with no signs of wear whatsoever. In between, I have bought gardiner brushes but have always returned to the Vikan.
