Learn how to use the Deckelöffner TOM to easily open stubborn jar lids without damaging them. Step-by-step guide included.

Quick Answer

Use the Deckelöffner TOM to gently lift the edge of a stubborn screw lid, breaking the vacuum seal so you can twist it off effortlessly.

Why TOM Works Without Damaging Lids

Many lid openers rely on brute force or sharp edges that can dent or scratch the lid. TOM works differently: it slides under the lid's edge and pries it upward just enough to release the internal vacuum. Once the seal is broken, the lid rotates freely with little effort. Because TOM doesn't grip or torque the lid, the lid stays intact and can be reused.

Steps to Open a Stubborn Lid with TOM

Position TOM Under the Lid Edge: Hold the jar steady with one hand. With the other, slide the thin end of TOM between the lid and the glass rim. Work it in gently until you feel it catch the lid's edge. If the lid is very tight, tilt TOM slightly upward as you slide it in.
Lift the Lid to Break the Vacuum: Press down on the handle of TOM (the part you're holding) to lever the lid upward. You should hear a soft pop or hiss—that's the vacuum releasing. Do not pry too far; just a small lift is enough. Stop as soon as you hear or feel the vacuum break. Over-prying can bend the lid.
Twist the Lid Off Normally: Once the vacuum is released, grip the lid with your fingers and twist counterclockwise. It should open with little resistance. If it still feels tight, repeat the first two steps at a different spot on the rim. If the lid still sticks, the jar may have a safety seal that needs a second lift.
