I decided to make a more apropriate holder for the little olivewood knife that mother took a liking to so at her 90th birthday at the weekend I said I would get it sorted this week so this is what I came up with. I didn't have a large enough piece of olivewood but I think the contrast of the walnut is a better look anyway
This is what I did to make the little knife more available for her. It will be screwed onto one of her cupboard facings, be simple to retrieve and replace, while being secure in keeping.

The recess has to follow the curviture of the handle to get a good fit and have with enoug depth at the ase to give full support to the handle end
