I have this very special knife from a customer for a saya and handle upgrade. I have seen many Shige yanagi, but this one stands above them all. I think I have seen only one that came close. Tall and massive, would be the words to describe it.
So, I am thinking of making a saya for it that is only seen with 2K+ knives. Typically it's ebony, with a chamfered spine, groves and dots on the front side, angled tip, and finger recesses (no pin). I have done a simple version of it, but not in a tropical hard wood.
So this is a project I started. Wood is cocobolo, for both the saya and the handle.
I resawn the wood for the saya, and let it rest for a over a week. This is done to let the tension of the grain to normalize. My next step is carving. This is pretty lengthy and meticulous process, as the fit on the saya has to be precise.
I will post some pics over the next couple of days
