Found this tool while cleaning out my uncle's garage. It's a cast metal fork with three heavily-ridged tines about four inches long, with a crossbar between them about an inch back from the end, and an unpainted wooden handle. It has absolutely no markings on it. Nobody remembers where it came from.
Guesses so far include "raccoon prod", "spaghetti server", and "three-pronged blivet". Any ideas?
