In the message and description of the knife you said that his tanto is so unique that it was given its own name.
I did not say such a thing since it is not true that this knife has its own name.
I certainly said that this Tanto is a great design and that I like it much better than most other Tantos. Those are the same sorts of comments that I made about the 47, in fact. I may also have said that the knife is a totally unique which it is. Other's may claim to have the rarest of all balisongs and they may even present very impressive specimens to portent that title. But, the specific snakewood insert piece that you refer to is certainly a strong contender to that crown.
(However, if we were to hold a contest for the rarest and most exotic of all balisongs, that snakewood piece would not be my entry.)
However, will all due respect to Mr. Elishewitz, and a lot of deep respect is due to Mr. Elishewitz who I have met, he did not invent the Tanto nor did he invent the drop point. With some small research, I suspect that you'll find prior art for the Tanto dating back some thousand years or more and for the the drop point probably dating back at least a hundred.
Again, let me say that Mr. Elishewitz's implimentation of a drop point tanto as seen on that snakewood custom and as seen on several other examples that occupy high positions in my collection, is wonderful. I think it's the best rendition of the classic tanto that I've ever seen.
Certainly the 47's blade is inspired by that Elishewitz tanto. I think I commented about that in my Bladeshow article.
But, to the best of my knowledge, and I may be wrong, Mr. Elishewitz did not directly participate in the design of the 47.
