In my work I come across some interesting bits of wood from time to time. I’m not sure if it’s ideal but I have some quite thick prunings off a very large olive tree, they’ve been drying for years. I’ve used them for priests and for bill hooks. I’ve lately come across some seasoned bog oak , much of it has shakes but I’ve picked through and found some nice blocks about 8inches long x 5 x5 from dark brown/ grey to mostly deep ebony black. It’s rock hard and polishes up beautifully. If any one wants to try them I’m more than happy to send some through. If in some future date a little handle insert pops up in the post to cover the posts that would be a bonus, but not necessary. I’d just like to see them used.
