One-handed combination utensil (Nelson fork)

The utensil is named after Admiral Lord Horatio Nelson, who lost his right arm at the Battle of Santa Cruz de Tenerife in 1797. A specialised combination knife-and-fork was designed for him so he could dine independently with one hand.
The utensil combines a full-sized fork with a curved, rocking knife blade integrated near the tines. This configuration lets a person cut food using a rocking motion and then immediately pick it up with the tines without needing to switch between tools or use a second hand.
This example is likely to have been produced between the late 19th century and World War One. It was made by Elkington & Co., a premier English silversmithing firm founded in Birmingham. This company patented the first commercially viable electroplating process in 1840.
They were widely issued or gifted to amputees, veteran soldiers, or individuals who lost the use of an arm.
