This is a vintage canning jar lifter (also known as jar tongs or a jar wrench).
Before modern canning equipment, families used this tool during home preserving season. The metal arms grip the hot glass jars securely while you lift them out of boiling water, and the long wooden handle keeps your hands safe from the heat and steam.
It was an essential kitchen item for anyone who canned fruits, vegetables, jams, or pickles. The design makes it much safer and easier than using regular tongs.
