I made these today from 3/4" Cocobola about 9" long. I turned the blade to a taper, trimmed on a Bandsaw and finished up with a belt sander and some hand sanding. I Beall buffed and put on some Reanaissance wax.
With all of the horror stories I have heard about Cocobola causing severe reactions, turning it tends to make me a little cautious. I wear a nuisance dusk mask and keep the DC going. And wash my hands afterwards. Hope that is enough.
