Old Maryland Engraved offers a very unique style, which was perhaps inspired by Mayflower, an earlier design of Kirk. First made in 1936.
HH stands for "Hollow Handle", which means that the item has been made with a hollow sterling silver handle, and a stainless steel utensil has been inserted into it. Generally, the dinner knife handle is used for serving pieces, and a smaller version is used for the Butter Knife and Butter Spreader.
