Cumaru was the driver here, that I’d never worked with it (as true of most woods) and that, having designs to make a few other things with it, to make a spoon would be a good way to learn how it responds to tools.
I cut the shape with a jigsaw and a Ryoba. The bowl I did as a tiered excavation with a router, later to be smoothed with a few different bits via Dremel.
Sanded to 220, standard finish of tung oil cut 50/50 with limonene. The wood was delightful to work, heavy, holds detail, beautiful smell.
