Not sure how tiny these tools have to be but........My first thought for a "whisk".....blow up a small oblong shaped balloon just until firm...use royal icing to pipe thick lines (for sturdiness) in the shape of the wired end of the whisk....let this dry completely before deflating the balloon.  Now, like I said, this was what just comes to mind, I've never tried it.  A Slotted spoon should be relatively easy...using fondant or gumpaste, cut an oval shape....cut "slots" out of the center of it and lay it to dry on something rounded to get the shape.
