Words fail me Ian, those are really beautiful, the contrast between the ebony and maple is an inspired choice.
Is dovetailing the correct description? I can’t see any dovetails at all, inside and out, it looks like marquetry where one piece of work is inserted into a gap carved into the surface of the other. The small animals on the handle are exquisite, some real skill on show there.
You could make a living carving them for tourists I’d imagine, wouldn’t even know where to start with a value but I’d imagine quite a lot.
