I have a 35mm Kabuki brush that I enjoy using as a shaving brush. The base is just the little black plastic cap that these things come with, and I'd love to find something better for a handle. However, since no one makes 35mm knots, none of the artisans I'v talked to have bits to drill that kind of knot bed. Does anyone have any ideas of what I could use for a handle? I'm open to any ideas, even stuff thats a bit out of the box if its all that might work. Thanks for any ideas you all might have.
