if i were to do a "samurai sword" motiff, i would pay particular attention to the ringwork above the grip.
the samurai sword's hilt, as in everything japanese, was given careful consideration with elaborate/ornate detailing. in fact sword hilts are quite collectable for those who are into japonisme.
so MY cue version of a samurai sword would have a thick(maybe 1" or +), ornate ring design that would incorporate something cue-like,,,maybe a josey style fleur de lais with some japanese design - above the grip,,,,,,,no points(gaboon or african blackwood in the nose and butt),,,,,,,stack wrap(and i HATE stake wraps but they would be appropos in this case),,,,,,,and an inlay design that,,,,,hmmmmm, maybe i should approach richard black with with my idea.
i can see richard, schick, and maybe josey in executing such a design.
