Here is a set of six vintage sterling silver picks, each with a different design finial. The blade is marked “Sterling” with no maker’s mark.
They measure from approximately 3 inches long to 3 and 1/4 inches (those with the elongated shape finials). Total weight is 21.9 grams.
I have seen similar picks (actually some identical) with the mark “TOW Sterling Creations”. I have seen others with a ” T C ” in a circle mark. I have also seen boxed sets where these are called “Snak Piks”.
I think they certainly could be used for canapes or hors d’oeuvres and they would work well as cocktail picks in the smaller vintage size Nick and Nora glasses. Keep in mind these are three inches or slightly larger and wouldn’t work well in the larger size martini glass common today.
These picks are available for sale here at my Etsy shop: https://www.etsy.com/listing/631672955/sterling-silver-cocktail-picks-set-of
