You find the can opener in the drawer under three takeout menus, a ball of string, and the little screwdriver Mom used for everything. Dad says it works fine. Then he picks up a can of soup, studies the lid, and puts it back.

This is not really a can opener question. It is a lunch question.
If opening one can now requires a strong grip, a steady counter, good light, and several bits of cleanup, Dad may decide that crackers count as lunch. He will not announce this as a household problem. He will simply stop choosing foods that make the problem visible.
Your job is not to reorganize his kitchen while he is looking the other way. It is to find out whether the opener, the cans, and the place where he uses them still fit the way he cooks.
Start with one real can
Do not test the opener by turning its handle in the air. Ask Dad to open something he would actually eat. Soup, beans, fruit, tuna, whatever belongs to his ordinary day.
Stand nearby without reaching in too soon. Watch the whole trip. Where does he get the can? Can he read what it is? Where does he set it down? How does he attach the opener? What does he do with the loose lid? Can he carry the opened can to the sink, stove, or bowl without catching a sharp edge?
You are looking for the point where an ordinary task becomes an argument with an object.
Maybe the opener skates around the rim. Maybe its handles are too narrow for his grip. Maybe the cutting wheel is dull and he has learned to squeeze harder. Maybe the drawer is low enough that getting the tool is worse than using it. Dad may call all of this fine because, eventually, the can opens. Eventually is doing quite a bit of work in that sentence.
Fit the opener to his hands
A manual opener should stay attached to the rim without Dad having to clamp it with all his strength. The turning handle should be large enough for him to hold comfortably. Its direction should make sense to him, and the handles should not pinch his fingers when he closes them.
Ask him what bothers him about the current one. Do not accept “nothing” until you have watched a can being opened. More useful questions are: Does it slip? Does the turning handle hurt? Can you tell when it has gone all the way around? Is it hard to release?
If you compare replacements, bring home only one or two serious candidates. Look for handles he can wrap his fingers around, a turning knob he can grasp, and a cutting mechanism that is easy to line up. If the opener leaves the cut lid sharp, make sure Dad has a way to lift and discard it without putting his fingers against the edge.
An electric opener may help if squeezing and turning are the problem, but it creates its own questions. Can Dad place the can correctly without holding its full weight in the air? Is the control obvious? Does the magnet hold the lid? Can he remove the can without spilling it? Can he clean the cutting part? Is there a convenient outlet where the cord will not cross the work area?
Choose by what Dad can operate from beginning to end, not by which opener looks clever in the box.
Fit the cans to the meal
A large can may look practical until half of it sits unidentified in the refrigerator. A tiny can may be easy to lift but hard to hold still under the opener. Pull out several cans Dad already owns and compare them with the meals he actually makes.
Check whether the labels are readable where the cans are stored. Similar cans can become a guessing game in a dim cupboard. Put everyday choices at eye level with the front labels facing out. Keep duplicate cans together so he can see what he has without conducting an archaeological dig.
Notice the portion after the can is opened. If Dad eats only part, does he have a container he can open and close easily? Is there a marker or simple label nearby so he can name what went into the refrigerator? If leftovers routinely become mysteries, smaller cans may fit his household better.
Pull tabs are not automatically easier. Ask Dad to open one. A small ring can be difficult to lift, and a lid that releases suddenly can spill the contents. The right package is the one he can open safely and reliably, not the one that advertises convenience by putting a tiny metal loop on top.
Fit the counter to the job
Give the can a firm, dry place to stand. Clear enough counter space for the unopened can, opener, bowl, and spoon. If Dad has to balance the can on the edge of the sink because the useful counter is covered, the opener is only one part of the trouble.
Put the opener near the food it opens, unless Dad prefers another spot. A shallow drawer at a comfortable height may work better than a crowded crock or a low cabinet. The correct home is the one he remembers and can reach.
Check the light directly over the work area. Shadows can make it hard to see whether the cutting wheel is on the rim. Also check whether the can slides while he works. A clean, dry counter or a nonslip mat can give him a steadier starting place.
Then follow the food onward. Can Dad pour soup into a pan without twisting awkwardly? Can he drain tuna without pressing a sharp lid into the can? Would a small strainer make that step easier? Can he lift the pan once it is full?
You may discover that the opener is fine and the saucepan is the real bully. That still counts as a useful answer.
Let Dad choose what stays
If the old opener belonged to Mom, Dad may not want it replaced just because you found one that works more smoothly. Ask before removing it. You can keep the familiar opener in the drawer while placing the easier one where he can try it.
Do not turn lunch into an equipment demonstration. Make the meal, sit down, and notice whether the new arrangement reduced effort. Dad gets a vote on where the tool lives, which foods he keeps, and whether the whole thing feels worth using.
The best fit may be a better opener. It may be cans in a reachable cupboard, a clear patch of counter, and two soups he genuinely likes. It may also be deciding that canned food is not his route to lunch at all.
What to do tonight
Choose one can Dad would willingly eat. Ask him to show you how he opens it. Watch without correcting him.
Check four things: whether he can reach the can and opener, attach the opener, finish the cut, and handle the lid. If any step fails, make tonight's meal another way. Do not ask him to prove it twice.
Clear one steady work space. Put the opener, a bowl, and a spoon within easy reach. Move everyday cans to a shelf Dad can reach without bending deeply or climbing. Throw away any can that is bulging, leaking, badly rusted, or sharply dented at a seam.
Before you leave, ask Dad to choose tomorrow's lunch. Put everything needed for that meal together. The goal tonight is not a perfect kitchen. It is one lunch he can see himself making.
When to ask the doctor
Tell Dad's doctor if using the opener reveals a new or worsening change in his hands, strength, coordination, vision, or ability to follow a familiar sequence. Mention what you actually saw, such as dropping the can, being unable to turn the handle, missing the rim repeatedly, or forgetting what to do next.
Ask sooner if the change appeared suddenly, if Dad injured himself, or if the same difficulty is showing up with other ordinary tasks such as holding a mug, buttoning a shirt, or using utensils. You are not naming the cause. You are giving the doctor a clear picture of what changed at home.
The good-week card
Add this line: Dad opened one food he chose, made the meal, and ate it.
