The scales for the folding are Lignum Vitae, my first time to use this wood. A deserved reputation, was a lot of work to shape. A friend of mine was a "bobby" in Birmingham, England, and said his nightstick (truncheon to him) was made of this, and was almost as indestructible as Captain America's shield.
The paring knife's scales are Macassar Ebony, and while pretty hard, much easier to work with. I just put some Briwax on it, which seems to be good for kitchen work.
I only finished these about a week ago, but already using daily. My wife loves the hefty little paring knife, so will probably retire the ebony Heinkel we've had for 30 years ... or give it to one of our kids.
