I'm going to nix the hide scraper as a possibility. Hides were a major source of income in California before the Gold Rush. The hide trade was the major part of the California economy. There are tanner's scrapers, which look a lot like drawknives, and there are scrapers used in the preparation of fresh hides. These latter have the working end of the tool at right angles, sometimes more than a right angle, for removing bits and pieces of stuff, connective tissue, fat, scraps of meat, etc. Scrapers are pulled across the hide, hence the angle of the blade. Some are lightly toothed, others are not.
Working at an open hearth kitchen fireplace means differences in even common tools like spatulas. The photos show a variety of spatulas. These are all blacksmith made, as is jess m's piece. They are all made to hang, as they would in this kind of kitchen.
Actually, I believe that the last photo is not a spatula as identified, but another forgotten kitchen tool, the salamander. Salamanders were heated very hot in the fire, and used to sear large pieces of meat (think large roasts) so that the juices would be sealed inside while the meat was cooked over an open fire on a spit.
