Balisongs And Caviar A Balisong Collector Special Exhibit C23 C23 was made for me and is in my collection. The design you see here is not the original design for this knife. But, when we received the Mokume-Gane material from Mr. Thomas, it was very clear that material was more beautiful that we could have imagined. To have implemented the original design using this material would have been a crime, a waste of this rare material. So, the entire knife had to be redesigned. Even the Damascus steel for the blade had to be set aside for a different project and new steel procured. I think it all turned out pretty well, though. And we'll do the original design later.
