This is some old stock figured Claro Walnut that used to belong to a gunsmith who used it for high end gun stocks.
I have cut these into book matched sets that are large enough to make a saya/scabbard for most kitchen knives. Some knife makers might use one of these to make matching scales for knife handles or for display box tops.
There may be a couple fine hairline checks at the edge of some pieces so you will want to position your pattern so they will be trimmed away when you shape your project. I left these sets large instead of trimming away the small flaws at the edges. This is natural wood, it has not been chemically stabilized.
To see what is available just click on the photo.
This is one of the sets I liked.
