“Most sharpeners get one thing wrong.” A 73-year-old knife grinder explains what it is – and why his last 212 are now half price

After 68 years, a small grinding shop in Sheffield closes for good on 30 November. The man behind the counter spent three winters building a little machine so his customers would never need him again. Now his hands have made the decision for him.

For 68 years, people in Hillsborough have carried their blunt knives to the same narrow shopfront on Middlewood Road. They come in wrapped in tea towels, in newspaper, in the cardboard sleeve they were sold in twenty years ago. Wilf Staniforth unwraps each one, runs his thumbnail across the edge, and usually says the same thing before the customer has finished explaining.

“It isn’t worn out. It’s blunt.”

Wilf is 73. He took over the shop from his father in 1981 and has stood at the same bench ever since, sharpening kitchen knives and mending the small appliances nobody else on the street would touch. On 30 November, Staniforth & Son closes for good. There’s no one to take it on, and Wilf’s hands, as he puts it, “have started making the decisions.”

The closing is only half of it. The other half is the thing Wilf built in the back of the shop, and why he’d rather see the last 212 of them in British kitchens than in boxes on a shelf.

“Most of What Comes Through That Door Was Ruined at Home”

Ask Wilf what he sees on his counter and he doesn’t start with blunt knives. He starts with damaged ones.

“A blunt knife I can sort in a minute,” he says. “What breaks my heart is the knife somebody tried to fix themselves.” Edges chewed into little saw teeth by a ten-pound pull-through gadget. Tips rounded off. Scratches up the side of the blade. A good carving knife with a nick in the middle from a honing steel held at the wrong angle.

And then there are the people who never tried at all. They just pressed harder. The tomato flattens instead of slicing. The onion skin squeaks and the blade skids sideways. The Sunday joint gets sawn instead of carved. Most of them blame the knife, or themselves, and buy another set.

“People think a blunt knife is the safe one,” Wilf says. “It’s the other way round. A sharp knife goes where you point it. A blunt one needs force, and force is what makes it jump off the tomato and into your thumb.”

Butchers and chefs have always known this. They don’t have more talent than you do. They have a routine and a reliable angle. Everybody else was supposed to have one too, once.

The Wheel on Middlewood Road

Wilf’s father, Harold Staniforth, went into Sheffield’s cutlery trade at fourteen as a table-knife grinder, one of the “little mesters” who rented a wheel in a works by the river and ground blades for the big firms by the dozen. In 1958, with a second-hand wheel and a few years’ savings, he opened his own place in Hillsborough and painted the sign himself: Staniforth & Son, Grinders.

“Butchers came in from all over the north end of the city, and on a Saturday the queue went out the door,” Wilf says. “I was in the shop from the time I was seven. My job was to hand him the next knife and keep my fingers out of the way.”

Harold had one rule, and he repeated it so often that Wilf still hears it in his father’s voice: The angle does the work, not the arm. Hold the blade at the same angle every pass, let the stone do its job, and even a cheap knife will take an edge.

Then the works went quiet. Knives got cheap. Block sets arrived with a shiny honing steel that most people assumed was a sharpener. It isn’t: a honing steel only straightens an edge that’s already there. The gadgets came next, and every one of them landed on Wilf’s counter sooner or later.

Wilf has a name for that drawer. He calls it “the museum of good intentions.” The honing steel that never sharpened anything. The pull-through gadget that tore the edge into a ragged line. The suction-cup sharpener that wouldn’t stick to the worktop. The whetstone bought after a YouTube video, used twice, and put away when it turned out you need years of practice to hold the angle by hand.

“None of these people were lazy,” he says. “They tried. They just never had a tool that held the angle for them. So they’d come to me once a year, and spend the other eleven months cutting with blunt knives.”

Three Winters in the Back of the Shop

The idea came from his customers. Around 2021, the same faces kept coming back a few weeks after he’d sharpened their knives, embarrassed, asking whether there was something they could use at home. “A widow from Walkley told me she couldn’t carve the Sunday roast any more, because her husband had always done the knives,” Wilf says. “What was I going to sell her? A stone she can’t use? One of those gadgets I spend half my day putting right after?”

So Wilf did what a man who has mended small motors for four decades does. He started building one. Three winters, at the back bench, after closing.

He knew what he didn’t want. No coarse grinding wheel, because that’s what gives electric sharpeners their bad name. No open, spinning wheel that throws grit across the kitchen. Nothing big enough to need its own spot on the worktop. And nothing that asks the user to hold an angle, because that’s exactly what nobody can do.

What he ended up with is small enough to live in a drawer:

• A fine ceramic wheel instead of a coarse grinder. Ceramic is what the old hands used on the bottom of a mug. It takes off only a whisper of steel per pass and leaves a clean, smooth edge.
• Two fixed slots, one for each side of the blade. The angle is built in. You don’t hold it, you don’t guess it, you don’t need a steady hand.
• A clear protective cover over the wheel. The fine metal dust stays inside instead of landing on your worktop, and your fingers stay away from the wheel.
• A flat finishing stone on top for a quick touch-up between sharpenings.
• Power from a USB cable. “Every kitchen in Britain has a phone charger,” Wilf says. “Why should you need another plug?”

Then he tested it. Over three hundred knives went through the prototypes before he built the first one he’d sell: knives from the church hall kitchen down the road, from his regulars, from neighbours who’d heard what the old man at the grinding shop was up to.

“Those Ads Say Electric Sharpeners Eat Your Knives. They’re Half Right.”

If you’ve been online lately, you’ve probably seen the adverts for rolling sharpeners that rank electric sharpeners dead last and warn they’ll “grind years off” a good knife. Wilf doesn’t argue with that. He argues with what it leaves out.

“They’re talking about the old machines,” he says. “Coarse stones, no guide, the sharpener on the back of the tin opener. Those will take a knife apart. I’ve seen hundreds of them.” The difference, he says, is the abrasive and the angle. A fine ceramic wheel and a fixed slot do the same thing a good whetstone does in good hands, just without the years of practice.

Kerry Hinchliffe has run a knife-sharpening stall at a Sheffield farmers’ market for 19 years and has watched Wilf work since she was an apprentice. She was sceptical. “I’ve spent my whole career telling people to keep electric sharpeners away from their knives,” she says. “Then Wilf handed me one of his and a box of my customers’ knives. The edges came out clean. No chips, no saw teeth, no rounded tips. For the everyday knives people actually own, it does the job I do, in the time it takes to boil the kettle.”

She is just as clear about what it’s not for, and so is Wilf. It’s made for straight-edged kitchen knives: cook’s knives, carving knives, paring knives, utility knives, the old favourite from your mum’s drawer. It is not for serrated bread knives. Nothing that pulls through a slot sharpens a serrated edge properly, and anyone who tells you otherwise is about to ruin yours. It also isn’t meant for single-bevel Japanese knives that are sharpened on one side only.

How It Works, Even If You’ve Failed With Every Sharpener Before

This is the part Wilf cares about most, because it’s the reason he built the thing. His test was simple: could the widow from Walkley do it on her own, at her own worktop, without him standing next to her? She could. It took her about a minute.

People ask Wilf whether a USB motor is strong enough. It is, he says, as long as you do what most people find hardest: stop pushing. “Everybody who’s ever used a blunt knife has learned to press. Here you do the opposite. If you lean on it, you’re working against the wheel. Light pulls, and it does the rest.”

It makes a quiet whirr while the blade is in the slot, a few seconds per pull. A whole block of knives takes about ten minutes. After that, a few pulls every couple of weeks keeps them there.

The Knife You’d Stopped Using

The most common thing Wilf’s customers tell him isn’t about a new knife. It’s about an old one. The carving knife from the wedding set. A mother’s paring knife with the handle worn pale. The heavy cook’s knife that got demoted to the back of the drawer because “it doesn’t cut any more.”

“Even a cheap knife will take a good edge,” Wilf says. “Keeping it is the hard part, and that’s what this is for.” Christmas dinner is the moment he thinks about. The whole family round the table, everyone watching, and the turkey either comes apart in clean slices or gets sawn into shreds. “That’s a minute of sharpening on Christmas Eve. That’s all it takes.”

Here’s how it compares with what most people already have in the drawer:

Why the Last Ones Are Half Price

Wilf put every sharpener together himself, at the back bench, the same way he mended motors for forty-odd years: fitting the wheel, setting the slots, running a knife through each one before it went in the box. Since spring 2024, about 1,400 have gone out the door. The first ones went over the counter to people who walked in with a knife wrapped in a tea towel. Most of the rest went out by post once his granddaughter started taking orders online.

Last winter, the arthritis in his hands got bad enough that the fine work stopped being possible. “Setting the slots is a hair’s-breadth job,” he says. “Some mornings now I can’t close my hand round a screwdriver. I won’t send out something I can’t stand behind.”

So the shop closes on 30 November. His granddaughter Libby, 20, who handles the shop’s online orders, counted what’s left on the shelf: 212 finished sharpeners, each one tested. There won’t be more. Wilf wanted them gone before Christmas, into kitchens, not into a lock-up.

What the First Owners Say

Libby asked a few of the people who bought one to send a photo from their kitchen. Four of them did.
