Among some military memorabilia from the Spanish American War, I found the item I will picture below. It is made of steel, is eight inches long, and is only about a sixteenth of an inch thick but is still very rigid. I have no idea what it might be. The ridges behind the head are quite sharp, almost like something that might be used to saw something, but it would be hard to handle. If anyone has any idea what this might be, I'd appreciate hearing from you.
