How to open a jar with one hand
Quick answer: Brace the jar so it can't spin, between your knees or trapped by a drawer, then twist the lid with your free hand. Letting air under the lid with a spoon tip first makes the twist much lighter.
Not quite your situation? Opening jars with a weak grip or see every reason opening jars gets hard.
A jar normally opens with two opposite twists: one hand turns the jar one way while the other turns the lid the other way. With one hand on the lid, the whole jar just rotates with it, however hard you grip. So the first job is stopping the jar from turning, and loosening the lid comes second.
Try this first (no purchase)
- Hold it between your knees. Sit on a firm chair and squeeze the jar upright between your thighs, just above the knees. Wrap a dish towel around a glass jar so it doesn't slip, then push down on the lid with your palm as you turn.
- Trap it with a drawer. Open a top drawer a few inches and stand the jar inside, right behind the drawer front. Push the drawer shut with your hip until the jar is pinched against the edge of the countertop, and keep leaning while you twist. This works for jars tall enough that the lid sits above the counter.
- Use the sink corner and a wet cloth. Soak a dishcloth, press it flat against the sink floor to squeeze most of the water out, and stand the jar on it in a corner. A rubber glove or a second damp cloth over the lid helps your palm grip. The sink is lower than the counter, so you can lean more weight down through your hand, and that downward pressure is what stops the jar turning.
- Break the seal before you twist. A lid that won't budge is usually held down by the vacuum inside the jar. With the jar braced, slide the tip of a teaspoon under the lid edge and lever gently until you hear a pop. Skip the hot-water trick, which leaves you holding a wet, hot jar with nothing to steady it.
- Close it loosely next time. When you put an opened jar away, turn the lid only until it stops, with no extra squeeze at the end. Store it upright so a loose lid can't leak.

Check price on Amazon (opens new tab)- Why it works
- It clamps and turns the lid by itself after a 3-second press, and you don't hold the opener while it runs, so one hand can manage the whole job.
- Who it won't suit
- All our quotes come from people with arthritis rather than one-handed users, and it only fits lids from 1.2 to 3.5 inches, not plastic ones.
What reviewers report

- The pad glues the jar to the counter so it cannot spin, which frees your working hand for the lid, and at 80 mm across it holds a can or a bottle the same way.
- Who it won't suit
- Pads are not a lever: a lid that is genuinely stuck still needs your own turn, and the sticky face has to be rinsed and dried again once dust dulls it.

Most reviews come from people preparing for shoulder surgery or recovering from one, with an arm out of action for weeks, and from a stroke survivor who needed to open jars with one hand. — Our summary of customer reviews on Amazon · read the reviews (opens new tab)

Check price on Amazon (opens new tab)- Why it works
- Place it on the lid and press the button: two vice grips clamp lids from 1.2 to 3.5 inches and the motor does the twist. One reviewer with limited grip after cut tendons uses it.
- Who it won't suit
- It takes two AA batteries that aren't included, and the maker doesn't recommend it for plastic jars holding liquids.

Reviewers describe the specific losses they are working around: arthritis in the thumbs bad enough to weaken a grip, and cut tendons that left one hand with little strength. — Our summary of customer reviews on Amazon · read the reviews (opens new tab)

Check price on Amazon (opens new tab)- Why it works
- The mount holds the lid while the jar stays below, and the listing says you turn it with just one hand; it adjusts itself to lids from 0.6 to 4.7 inches.
- Who it won't suit
- Our quotes come from people with arthritis and weak grip, not from one-handed users, and fitting it needs a screwdriver and a cabinet edge.
What reviewers report
One reviewer with arthritis calls it essential for weak hands; another says the grip is poor. Two reviews that disagree is thin evidence, and we treat it that way. — Our summary of customer reviews on Amazon · read the reviews (opens new tab)
What not to buy for opening jars with one hand
- Handheld cone or ring jar openers — they're built for one hand to hold the opener on the lid while the other turns the jar. With one hand, nothing turns the jar, so it spins along with the opener.
- Rubber grip pads used on their own — a pad helps your palm grip the lid but does nothing to hold the jar still. It's useful on top of a lid once the jar is braced, not as the whole answer.
Buying this for someone else?
- Which hand is free, and is it their writing hand? Someone left with their non-dominant hand will find fine tasks harder than you might guess. Scissors and some knives are made for right or left hands, so check before ordering.
- Weeks, or for good? For a cast or sling, cheap and portable makes sense. After a stroke, an amputation or with a limb difference, tools that mount to a counter or cabinet are worth the setup.
- Where it would go. Mounted openers need a flat cabinet underside and screws, which renters may not be allowed to fit. Suction tools need a smooth counter. Look at the kitchen or bathroom before you order.
- What's already in the drawer. Ask what they've tried and whether an occupational therapist has already given them something. Most people have a gadget that didn't work, and knowing why it failed is the most useful thing you can learn.
