The Individual Caviar Knife can easily be confused with the Flat Handled Butter Spreader. And, to complicate matters, there is no consistent size, even among patterns by one manufacturer, as you can see here by the examples of Caviar Knives in Tiffany patterns. No two are the same length.
One of the neat smaller place forks in any pattern. The Oyster Fork (not ot be confused with the cocktail fork) in each pattern tends to be a little unique. I have posted on these several times before because they are so plentiful and so interesting. Repousse by Kirk Stieff
I posted earlier on the Overcup Tea Strainer, an over the cup piece used to strain tea leaves when making a cup of cup. This is a very elaborate piece given there is a lot of area for the designers to work with. Stieff Rose by Kirk Stieff
