Crafted from thick, rust-proof stainless steel, it’s built to last, making it a staple in your kitchen for decades to come. Compact and easy to store, it’s the perfect accessory for anyone who loves canning, preserving, or using Mason jars for everyday storage. Multi-functional opener: * Flat canning lids - put the "hook" under the top, then lift the handle up. * Screw on Mason full lids - put the "arms" of the opener under the lid and push the handle down to let air into the jar and release the pressure. Then unscrew the lid normally. * Lug style non-Mason lids - common on store-bought glass jars - put "hook" under top, then lift handle up slightly to release pressure and twist right.
