In the 19th century, upper class homes had serving utensils for each part of the meal.  Fish servers were used to portion and serve fish.  They were often made of silver or silver plate.  The knife has lovely openwork, which in addition to being visually attractive, allowed excess liquid to drain before serving.

 

 

Sheffield silver plate was produced in Sheffield, England from the mid-1800s.  Unlike solid silver, Sheffield silver plate was made of a base metal coated with a thin layer of silver.  This technique allowed manufacturers to produce pieces that looked like solid silver at a much lower cost.  Silver plate was popular for its affordability and for the intricate designs that could be produced on its surface.  Common items included candelabra, flatware, tea sets and serving trays.  Despite its lower cost, Sheffield plate is highly sought after for its elegant design and high-quality construction, making it a popular choice for antique collectors and silverware enthusiasts.
