Kitchens are filled with tools designed to make cooking easier, but some gadgets take specialization to an extreme. These "unitaskers" — devices that perform one specific function — range from mildly unnecessary to downright absurd. In this exploration, we rank some of the most bizarre single-use kitchen gadgets and delve into the stories behind their creation.

Starting with the herb scissors, a tool that promises efficiency but often falls short due to its cumbersome cleaning process, we move up the scale to the strawberry huller, which works on only 60% of strawberries. The avocado slicer, designed to streamline a multi-step process, introduces new hazards while solving others. Then there’s the egg cuber, a device that reshapes hard-boiled eggs into cubes for optimized bento box packing — a niche benefit that few actually utilize.

But it’s the motorized ice cream cone that truly defies logic. This gadget rotates the cone so your tongue doesn’t have to, solving a problem that arguably never existed. Each of these gadgets reflects a blend of ingenuity, marketing, and human curiosity about convenience.

The unitasker phenomenon isn’t new; it dates back to the Victorian era, where specialized tools like asparagus tongs signaled social status. Today, cheap manufacturing has made these gadgets accessible impulse purchases, often priced below the "threshold of regret."

While some unitaskers are undeniably pointless, others possess a quirky charm that makes them oddly endearing. Whether they’re solving real problems or creating new ones, these gadgets offer a fascinating glimpse into the intersection of innovation, consumer behavior, and the occasional absurdity of modern life.

#2273: The Curious Case of Kitchen Unitaskers

Corn
Daniel sent us this one, and I have to say, it might be the most personally relatable prompt we've received in a while. He wants a ranked countdown — ascending absurdity — of the most pointless single-use kitchen gadgets ever sold. Egg cubers, avocado slicers, banana slicers, motorized ice cream cones, electric s'mores makers, herb scissors, quesadilla makers, hot dog toasters, strawberry hullers, pancake batter dispenser pens. Ranked from "okay, I can see why someone bought this" all the way up to "who approved this in a board meeting." The question underneath all of it: how did any of these things exist?
Herman
I have a banana slicer story.
Corn
Of course you do.
Herman
A patient — this is back in my pediatrics days — her mother comes in for the kid's well visit, and she's just vibrating with excitement. Not about the kid. About a banana slicer she bought. Described it to me for about four minutes. It has a handle, it has these little parallel blades, you press it down, the banana becomes uniform coins in one motion. She said, and I am paraphrasing only slightly, "Herman, it changed my mornings.
Corn
It changed her mornings.
Herman
It changed her mornings. And I'm sitting there thinking, the banana slicer was patented in two thousand and three by a man named Joseph DeCarlo. This device has existed for over two decades. It has been changing mornings for over two decades. And a knife has existed for roughly two and a half million years.
Corn
I want to be very careful here because I also own a banana slicer.
Herman
You do not.
Corn
I found it in the kitchen and I assumed it was some kind of leaf-pressing tool. I have been using it for leaf medicine for about six months.
Herman
That is genuinely upsetting.
Corn
It works great. Very uniform leaf sections. I don't know what DeCarlo intended but I think I'm getting more out of it than anyone who used it on a banana.
Herman
The global kitchen gadgets market is projected to reach one point two trillion dollars by twenty twenty-seven. One point two trillion. That includes serious equipment, obviously, but a non-trivial slice of that number is things like banana slicers and the eleven other objects we're about to discuss.
Corn
One point two trillion dollars of humans looking at a problem that a knife already solves and thinking, "but what if there were a dedicated unit for this specific task.
Herman
The unitasker phenomenon. We explored the psychology behind this pretty thoroughly in an earlier episode, so I don't want to retread all of that. But today we're not here to explain why people buy these things. We're here to look at the specific items and appreciate each one individually for the particular flavor of chaos it represents.
Corn
A connoisseurship of absurdity.
Herman
And I want to say upfront, some of these I have genuine affection for. There's a difference between useless and delightful. Some of these gadgets are both, and that's almost an achievement.
Corn
By the way, today's script is courtesy of Claude Sonnet four point six, who I imagine researched this topic with the same energy I bring to napping, which is to say complete commitment.
Herman
A natural fit for a topic about things that technically function but may not be strictly necessary.
Corn
I am necessary. Right, so we've got our list, we've got our ranking, ascending absurdity. Let's establish the bottom of the scale first, because I think there's a genuine spectrum here. Some of these gadgets, you squint at them and you can construct a defense. Not a good defense, but a defense. Others, there is no argument. There is only the void.
Herman
The void has a patent number.
Corn
The void has a patent number and it ships in two days with free returns. Let's do this. Honestly, it’s such a niche product—it’s practically a unitasker.
Herman
Speaking of unitaskers, what actually makes something a unitasker in the kitchen sense? Because I think the line is fuzzier than people assume.
Corn
It does one thing and only one thing and the thing it does was already handled by something you own.
Herman
That's close. I'd tighten it slightly. The defining feature isn't really the single function, it's that the function can't transfer. A whisk is technically a single-function tool, but the motion, the wrist mechanics, the basic physics of it, those translate. You can improvise with it. A banana slicer cannot become anything else. It is a banana slicer until it dies.
Corn
A knife, meanwhile, has been quietly doing everything for two and a half million years and asking for nothing in return.
Herman
Which is the real indictment. And this isn't a modern problem. The Victorians were obsessed with specialized kitchen equipment. There are Victorian-era asparagus tongs, asparagus cradles, asparagus servers, asparagus kettles. Dedicated hardware for one vegetable across four form factors.
Corn
The Victorians had a lot of feelings about asparagus.
Herman
They had a lot of feelings about demonstrating that you owned the correct object for every conceivable task. That's the social history underneath all of this. The gadget signals that you are the kind of household that takes this seriously. Whatever "this" is.
Corn
The banana slicer is actually Victorian asparagus tongs with better marketing.
Herman
The mechanism is the same. The difference is that somewhere between the asparagus kettle and the banana slicer, manufacturing got cheap enough that you could produce these objects at a price point where the impulse purchase becomes rational. The asparagus kettle cost real money. The banana slicer costs eight dollars.
Corn
Eight dollars is below the threshold of regret.
Herman
Below the threshold of regret, that's exactly it. Which is why we now have an industry. Shall we get into the actual ranking?
Corn
The gadgets await.
Herman
Starting at the defensible end.
Corn
Multiple blades stacked parallel, you run them through a bunch of chives or parsley, you get a pile of cut herbs in about four seconds instead of forty. I can see it.
Herman
The pitch is real. The mechanism is legitimate. You've got five blades running simultaneously, so you're reducing the task time by a factor of five, roughly. If you cook with fresh herbs every single day, the math almost works.
Herman
The problem is the cleaning. Each blade has its own gap, there are four gaps total, fresh herbs are wet and fibrous, and they pack into those gaps in a way that takes longer to clean than the time you saved cutting.
Corn
The gadget creates a new problem to solve the original problem, and the new problem is worse.
Herman
The net time savings across a typical use cycle is probably negative. But the scissor sits in the drawer and it feels purposeful. That's worth something psychologically.
Corn
It's a very confident-looking object.
Herman
It really is. Okay, moving up the scale.
Corn
Now here I want to play devil's advocate. Hulling strawberries manually with a knife is actually a slightly annoying task. You lose a lot of fruit if you're careless.
Herman
That's a real point. The huller is a small spring-loaded plunger, you press it into the top of the berry, twist, pull, the hull comes out cleanly. In theory you preserve more of the fruit than a knife cut.
Herman
In practice the spring mechanism on most of these is calibrated for an average strawberry, and strawberries are not average. They vary enormously. Small ones, the plunger goes straight through. Large ones, you don't get a clean extraction. So you end up with a device that works on maybe sixty percent of your actual strawberries.
Corn
That's a passing grade if you're being generous.
Herman
It costs about twelve dollars. So you're paying twelve dollars for a device that handles three-fifths of your strawberries adequately.
Corn
I respect the honesty of that failure rate. It's not pretending to be something it isn't. falls short on the physics.
Herman
The avocado slicer is where things start to get interesting.
Herman
The avocado slicer is typically a three-in-one tool. It splits the avocado, removes the pit, and slices the flesh in one sequence of motions. And on paper this sounds like genuine engineering. Someone looked at a multi-step process and designed a device to streamline it.
Herman
The pit removal mechanism is a plastic disc that you press against the pit and it grips via suction or friction and you twist it out. This works occasionally. When it doesn't work, you are pressing a plastic disc against a large slippery seed inside a fruit you are holding in your non-dominant hand.
Corn
That sounds like a liability waiver waiting to happen.
Herman
There is an entire genre of avocado-related emergency room visits. The avocado hand injury. Surgeons have a name for it. The avocado slicer was meant to solve this, and in the cases where the pit mechanism fails, it arguably makes it worse because you've added a plastic lever to the equation.
Corn
The safety gadget introduced a new safety hazard.
Herman
With slightly more mechanical advantage, yes. The slicing portion, to be fair, is actually fine. A plastic fan blade that cuts the flesh into uniform segments. That part works. It's the pit removal that's the problem, and that's the only part of the process that was actually dangerous to begin with.
Corn
They solved the easy part and complicated the hard part.
Herman
That's the avocado slicer in one sentence.
Corn
Now the egg cuber.
Herman
The egg cuber.
Corn
I have been waiting for this one.
Herman
A hard-boiled egg is an oblate sphere. The egg cuber takes that egg and, through the application of a hinged mold and significant manual pressure, reshapes it into a cube while it's still warm and pliable. The result is a cubic hard-boiled egg.
Herman
The answer, and I want to be careful here because there is an answer, is bento boxes. Uniform shapes pack more efficiently. A cubic egg tiles. Spherical eggs roll and waste space.
Corn
That is a real argument.
Herman
It is a real argument. It is also an argument that applies to approximately zero percent of the people who actually purchased an egg cuber.
Corn
How many people are optimizing their bento box packing density?
Herman
But the existence of the argument is what makes the egg cuber defensible enough to sell. You can tell yourself a story. The story involves geometry and efficiency and you are a person who takes their lunch seriously.
Corn
The egg cuber is a self-narrative device that happens to also reshape eggs.
Herman
The cubic egg, I'll say this, is unsettling to look at. There is something that the human brain did not anticipate encountering. A cube of egg. It feels like it came from a parallel universe where evolution took a slightly different turn.
Corn
A universe I want no part of.
Herman
The taste is identical, which makes it worse somehow. You go through the whole process, you have your cube, you bite into it, and it tastes exactly like a normal egg. The cube contributed nothing to the experience except a mild existential unease.
Corn
Worth the twelve ninety-nine.
Herman
Arguably worth it just for that moment of unease, which is more than some of these gadgets can claim.
Corn
The motorized ice cream cone, though. That's where we leave the defensible hemisphere entirely.
Herman
Oh, we are firmly in new territory with that one.
Corn
Walk me through the mechanism, because I need to hear you say it out loud.
Herman
You hold a battery-powered handle. The handle rotates. The ice cream cone sits in the handle and spins. You hold your tongue still. The cone comes to you.
Corn
The cone comes to you.
Herman
The innovation is that your tongue no longer has to move in a circle. The device does the circling. You are relieved of the rotational burden of eating ice cream.
Corn
I have to ask. What is the rotational burden? What injury or hardship prompted someone to file a patent on this?
Herman
There is no documented problem this solves. The human tongue is among the most dexterous and tireless muscles in the body. It does not fatigue during ice cream consumption. Nobody has ever set down a cone halfway through and said, I simply cannot continue, the rotation has defeated me.
Herman
Yet someone sat in a room, possibly a room with a whiteboard, and said, what if the cone moved instead?
Corn
Someone pitched this. Someone made a slide deck. Someone said, the market is ready.
Herman
The market, apparently, was ready. Not in enormous numbers, but they sell, which means there are people who looked at this object and thought, yes, this addresses something I have been experiencing.
Corn
I want to know what those people think they've been experiencing.
Herman
My working theory is that it's not about the ice cream at all. It's about the novelty of the object. You bring this to a backyard barbecue and it becomes a conversation piece. It becomes a thing you do. The ice cream is almost incidental.
Corn
It's a social performance device that also dispenses ice cream.
Herman
Which, if you frame it that way, has more utility than the egg cuber. At least the motorized cone generates a reaction. The egg cube generates unease. The motorized cone generates laughter, which is a real output.
Corn
I'm going to need a moment to process the fact that we just gave points to the motorized ice cream cone.
Herman
The grading system is relative. That's the thing about a scale. Everything is measured against the other items on it.
Corn
The electric s'mores maker.
Herman
Now here is a device that took something requiring fire, an open flame, the outdoors, the smell of woodsmoke, a stick, the entire cultural context of camping, and said, what if we did all of that on your countertop with a heating element?
Corn
They took a campfire experience and put it in a box.
Herman
In doing so, they stripped out every single thing that makes a s'more a s'more. The s'more is not really about the chocolate and the marshmallow and the graham cracker. Those are the ingredients. The s'more is about the fire. It's about burning the marshmallow accidentally and eating it anyway. It's about the imprecision of the whole thing.
Corn
The charred outside and the molten inside that you didn't fully plan for.
Herman
The electric s'mores maker produces a consistent, evenly heated marshmallow every time. Which is, culinarily speaking, the worst possible outcome.
Corn
You've eliminated the variance and the variance was the point.
Herman
And the environmental side of this is worth noting, because the s'mores maker is a good example of the broader problem. You've got a plastic and metal appliance, probably manufactured overseas, packaged in a cardboard and plastic box, shipped across an ocean, to produce a snack that a twig and a lighter could produce in thirty seconds.
Corn
The lifecycle analysis on that object must be extraordinary.
Herman
There was a piece in a design journal a couple of years back that looked at the carbon footprint of single-use kitchen gadgets as a category, and the finding was essentially that the manufacturing and shipping emissions of most of these devices will never be offset by their actual use. A gadget used twice a year for three years and then discarded has a per-use environmental cost that's staggering compared to a knife or a wooden spoon.
Corn
Most of these end up in landfill.
Herman
Because they're not built to be repaired and they're not built to be recycled. The mixed materials, plastic handle, metal blades, rubber grips, these don't separate cleanly. So the whole object goes into general waste.
Corn
Then someone buys the next version of the same gadget two Christmases later.
Herman
The gift economy is a significant driver here. A huge proportion of these things are purchased as gifts. And the gift dynamic removes the normal friction of the purchasing decision. If you're buying for yourself, you might pause and think, do I actually need a motorized ice cream cone? But if you're buying for someone else, the question becomes, is this funny and does it fit in a box? And the answer to both is yes.
Corn
The gift removes the accountability. Nobody has to live with the decision.
Herman
Except the recipient, who now has a motorized ice cream cone in their drawer.
Corn
Next to the strawberry huller and the herb scissors.
Herman
The drawer of good intentions.
Corn
Every kitchen has one.
Herman
Every kitchen has one. And the thing is, I don't think the existence of this drawer is purely a failure. There's something in the human impulse toward specialized tools that connects back to something real. We are a species that makes things. We look at a problem, even a trivial one, even an imaginary one, and we want to build a solution. The banana slicer is a bad solution to a non-problem, but the instinct behind it is the same instinct behind every useful thing we've ever made.
Corn
That's a very generous reading of the hot dog toaster.
Herman
I'm choosing to be generous.
Corn
The hot dog toaster, for anyone unfamiliar, is a toaster with cylindrical vertical slots. You drop a hot dog in one slot and a bun in the other, and it toasts both simultaneously.
Herman
Which, again, there is an argument. Toasting a bun improves a hot dog. That's a defensible culinary position. The device is trying to streamline a real step.
Corn
Except a toaster already toasts buns. You lay the bun flat in the slot.
Herman
The hot dog toaster is solving a problem that was already solved by the device sitting next to it on the counter.
Corn
It's a toaster that forgot toasters exist.
Herman
The hot dog cylinder, the vertical cylindrical slot, it's chrome-plated, it looks purposeful, it has the visual vocabulary of serious kitchen equipment. Someone put real design work into making this object look credible.
Corn
Which is its own kind of achievement. The design is working harder than the function.
Herman
That's true of quite a few of these. The quesadilla maker is another example. Hinged plates, non-stick surface, it clamps down and heats from both sides simultaneously. And the pitch is that you get a perfectly even quesadilla without having to flip it.
Corn
You do not have to flip a quesadilla in a pan. You flip it once. It takes three seconds.
Herman
The quesadilla maker saves you one flip and in exchange requires you to store a device approximately the size of a small briefcase.
Corn
The storage footprint is the real indictment of all of these. Kitchen storage is finite. Every one of these objects is displacing something else.
Herman
Collectively, the single-use gadget category is one of the biggest drivers of kitchen clutter, which is its own knock-on effect. People buy gadgets to make cooking easier, the gadgets accumulate, the kitchen becomes harder to navigate, cooking becomes more stressful.
Corn
The gadgets are undermining the purpose they were sold to serve.
Herman
The kitchen gadget industry, which as we noted is heading toward a enormous market size, is partly sustained by the problem it creates. You need a drawer organizer for the gadgets. You need a bigger kitchen for the organizer. At some point you
Corn
Need a storage unit for the storage unit.
Herman
At which point you have spent more on the ecosystem than on the original problem you were trying to solve.
Corn
What do you actually do? If someone is standing in a kitchen shop right now, eyeing a pancake batter dispenser pen, what's the test?
Herman
The one-task question. Ask yourself: does this device do something my existing tools cannot do, or does it do something they can already do, just with more steps and a worse cleanup? The pancake batter pen dispenses batter in controlled amounts for making shapes. A squeeze bottle does the same thing. A squeeze bottle costs two dollars, fits in a drawer, and also works for condiments, sauces, salad dressings, anything liquid you want to portion.
Corn
The squeeze bottle is doing twelve jobs. The batter pen is doing one, badly.
Herman
The squeeze bottle doesn't require you to remember which drawer you put the batter pen in, because you only use it during the three-week phase every eighteen months when you decide you're going to make pancake art.
Corn
The phase always ends.
Herman
The phase always ends. The device remains.
Corn
There's also the question of what you're actually bad at. Because some of these gadgets are solving a skill gap for someone. The avocado slicer, we roasted it earlier, but if someone has limited hand strength or dexterity, the integrated design might actually matter.
Herman
That's a real point. The honest version of the purchase decision is: is this solving a problem I actually have, not a problem I imagine I might have? The imaginary problem is where most of these live. You see the strawberry huller and you think, I do sometimes find hulling strawberries slightly annoying. But annoying is not the same as difficult. A paring knife solves annoying. You don't need a twelve-dollar spring-loaded mechanism for annoying.
Corn
The threshold question. Is this a real obstacle or a mild inconvenience I've briefly dramatized?
Herman
The second test is the drawer test. Imagine it in your drawer in six months. Not the day you buy it, not the first Saturday you use it. Six months in, when the novelty is gone and it's competing for space with everything else. Does it still earn its place?
Corn
If you can't picture yourself reaching for it in February, don't buy it in December.
Herman
Which is also, not coincidentally, when most of these are purchased.
Corn
The gift season creates a very specific kind of optimism.
Herman
And for gifts specifically, the better move is almost always consumables or experiences over objects. A good jar of spice blend, a nice olive oil, a cooking class. Things that get used up or leave no footprint.
Corn
Things that don't end up in the drawer of good intentions.
Herman
The drawer has enough occupants.
Corn
Which raises the actual question underneath all of this. Will the drawer ever empty? Will we reach a point where people just stop buying these things?
Herman
I don't know. The market data suggests no. That projection toward a trillion-dollar kitchen gadgets market by twenty twenty-seven is not a market in decline. It's a market accelerating.
Corn
AI is coming for the kitchen.
Herman
It already has. There are smart cutting boards now that weigh your ingredients and give you nutritional data in real time. There are connected air fryers that adjust temperature based on what you put in them. The gadget is getting smarter, which raises a interesting question about whether the unitasker problem gets better or worse.
Corn
My instinct is worse. A smart avocado slicer is still an avocado slicer. You've added a battery and a Bluetooth connection to a problem that didn't need either.
Herman
The connectivity doesn't change the fundamental geometry. But there's a version of this where convergence actually solves the problem. A device that does twenty things intelligently is not a unitasker. The question is whether the industry builds toward that or just keeps adding chips to single-purpose objects and calling it innovation.
Corn
The motorized ice cream cone with an app.
Herman
I am afraid that exists.
Corn
It probably does. Somewhere there is a Kickstarter.
Herman
There is always a Kickstarter. But I think the more interesting question is whether the next generation of home cooks develops a different relationship with the kitchen. There's a real movement, particularly among younger cooks, toward fewer, better tools. The knife skills revival. The cast iron renaissance. The idea that mastery of a small set of real tools is more satisfying than a drawer full of substitutes.
Corn
Which is not a new idea. It's just periodically rediscovered.
Herman
Every generation rediscovers it, usually after filling a drawer.
Corn
The drawer is the tuition.
Herman
Thanks to Hilbert Flumingtop for producing, as always, the most organized chaos in podcasting. And a quick word to Modal, who keep our pipeline running without complaint, which given the volume of gadget nonsense we've fed it today is impressive.
Corn
This has been My Weird Prompts. If you've enjoyed the episode, a review on Spotify goes a long way and we do read them. Even the ones that just say "egg cuber.
Corn
Until next time.
