Interesting piece, it all fits together well, but it's not quite my cup of tea. Loving the shoulderless wedge with a barber notch, and the colour of that spine. I like the worked spine somewhat, but personally think it would look better without the fancy wedge end of the scales, and without the stippling on the spine (just feels a bit too 'busy' with all that spinework, IMHO).
Also, please forgive my ignorance, but how does elephant bark ivory differ from normal ivory?
