Query: How can I rate it if one piece seems to be missing?

I think the item will be good when it is complete. I did get 14 pieces (counting the wooden block), but there is an empty slot in the block, which, I suppose, would be the place for another knife. Or not? In case it is to be like I received it, what is the empty slot for? Until I get an explanation, I'll rate the item a 2.Your comments will be appreciated.
