I don't know if a YCS has ever been offered in horn, but I have never seen one. I have several YCS's, each with 2 Kardas, but they are all wood. The kardas that came with the checkerboard model are really much smaller than the regular kardas, being only about 5-6" in length. Because I had the wood already, I wanted a horn one. I got the last one to the right in Yangdu's pic. The horn polishing and inlay was superb, as was the sheath. My only disappointment was on the butt of the handle, where there was a largish gap where the horn met the tang. It was filled with some type of putty, not laha I'm sure as it was way too soft. Had he exact consistency of dark, dried chewing gum, so who knows?
I spent a half-hour digging it all out with a pik, and cleaning out the hole. I plan to mix up some black epoxy or acra-glas tomorrow and filling it in. I doubt it will be noticeable at all when I'm done.
This is a great design and I can't believe it took us this long to realize what we had under our noses all along with the YCS's. I'm hoping to eventually snag an 11-12" model, like the neem handled #1 that was with the same batch. With the exception of the one with the checkerboard, every one of mine is exactly 9.5".
Don't have a pic yet, but with my photgraphy skill you guys aren't missing much.
