Nice old Tiffany sterling knife, help with date please

Lovely knife. Anyone able to help with its age please? It hasan armorial, but I need to resize the photo.

 

The pattern is called Wave Edge. https://www.sterlingflatwarefashions.com/Patterns/Tiffany5.html

Date of manufacture is likely relatively close to the date of the patent (1884) - certainly not decades later. I'll check to see if Replacements knows anything about when "discontinued."

 

Just noticed the T under the patent date. That puts it between 1892 and 1902.

Brilliant - huge thanks! I did wonder about that edge.
