Sal Glesser, owner of Spyderco knives, once said the handle of the knife is more important than the blade. Is the handle of the brush more important than the knot? I recently switched from a Semogue 830 to a Semogue 1800; and the difference in the brush handle for me at least was striking (bristles on both very similar). I never previously paid as much attention to the handle; wish I had years ago.
