Czechoslovskian enameled minature knife

While looking through my deceased grandfathers more secret of possesions we found the small knife. It was with his collection of pocket watches. Its 25mm im length closed. Silver with glittered enamel or glass. The only marking is the name czechoslovskia at the base of the Blade. Any help as to where i might find some info about it as i cant seem to find anything that resembles it on any sites i try. Many thanks.
