Took a shot at it and this was the result of my first attempt. The materials used were buffalo horn for the ferrule and end cap, nickle silver spacers and dyed Oregon maple burl from burl source. And here it is mounted on my Tanaka R2 pm 210mm wa gyuto. And here it is with my Tanaka 300mm damascus yanagiba with Stephan Keller handle. So that's it, my first attempt at a wa handle. Questions and comments are welcome and thanks for viewing.
