Jar lifters are specialized tools designed to help safely lift and handle hot jars during canning processes. They typically feature a pair of gripping arms that securely hold the jar's neck, allowing users to lift it from boiling water or a canner without risking burns or spills. These tools are essential for home canners and food preservation enthusiasts, as they provide a secure grip and reduce the chances of dropping jars. Using a jar lifter ensures that jars are handled safely, making the canning process more efficient and enjoyable for everyone involved in preserving food.
