Vintage child's butter knife made by the Regal Silver Co. (marked on back) probably from the 1900s to 1940s. This belongs to a Puss and Boots set, marked as such, also with an embossed Puss and Boots figure on the handles.  It is 5" long, made for little hands. Silver plate is tarnished (see photos), but this does not detract from the lovely look of this little knife. Very nice cross-collectible.
