The curved edge kinda leads me away from salamander tho, it takes work to make a curved edge, sharpened or not, there has to be a reason for it's being there, and it serves no purpose on a salamander,,,
Perhaps it's just a fancy cake serving utensil....
Anglesmith gives a plausible reason for the decorative touches: "Some of the best "whitesmithed" (finely filed and polished) work of the local village blacksmith (USA) was given away as wedding gifts..." Quite a few things were made pretty, especially if given as gifts. It takes no work to speak of to make a merely functional S-hook, but with a little more work (and pride) they can be made quite prettily.
The blade on Jess m's is about 5 inches wide, which kinda leaves out cake servers.
Too short for a salamander, and too thin to hold the heat. The wood is also too close, and would burn. I can't imagine trying to chop anything with this, given the length of the handle -- quite awkward. Choppers in early kitchens didn't look a lot different from the Disston food choppers made into the 20th Century, and even those can be a little awkward to use.
The tools used at an open hearth make things a little different. There are two sorts of griddles, both of which hang from a crane that swings in and out of the fire place. One has a lip like a frying pan, and is used for frying in a little oil or grease. The other is nothing more than a round of iron. For this second sort, a straight handled spatula would be ideal. There are more examples, called "bake stones," some with griddle cakes or bannocks cooking on them at:
