When giving a Tool/Sword by

/give @p minecraft:wooden_sword 1 16 {Unbreakable:1}

you will get something like in the screenshots below

It would be cool if it worked with the other values too, so mapmakers have a chance to make tools like "The Ye Olde Everlasting Sword".

But it is also a bug since it gives an unknown texture to something that can be achieved in a vanilla environment and should be fixed in some way.
