unique

I have been researching various ways to make segmented blanks. Mostly Celtic knots, but other stuff as well. I came across this image, just in an image search, but the link was to a defunct site that no longer exists. It seemed to be the only reference to this image I could find...and wow, these...

My mother sent me this walrus jaw bone from her recent trip to Alaska, so naturally I turned some! I added rings of turquoise, reminiscent of New Mexico, and Blackwood for contrast. I apologize for the blurriness, still haven't quite gotten the hang of photographing the pens.

I'm looking for some truly unique pen parts I can use - something finer than a Statesman or Junior Statesman - finer grade metal, unusual detail. Very high quality. Any ideas on a source aside from the basics at Woodcraft, Craft Supply, etc.?
