BJ - To me it looks like one of those shoe scrapers that you used to see next to an entry door back in the old days. The bladed part is pushed in to the ground leaving the top part out to scrape the mud/snow from your boots or shoes. Just a guess.
That first item looks like one of those belt buckle knives that came out a few years ago. The second is a cast iron pancake cooker or that's what my wife calls hers. Monty
Different parts of the country seems to have different names and uses for the skillet. In this area they are called "hoecake skillets". (fried cornbread)
