About a discovery from the 1950s, a gold medal at Chelsea, and a tool that respects the soil.
There are tools you buy, use, and replace after a few seasons. And there are tools you find: in a shed, in an estate, in the hands of someone who knows what good quality is. The story of the Thornett Trowel begins with the second kind. It’s the story of a hand trowel that no one had ordered, no one had designed for the market, and yet it did exactly what it was supposed to do. For more than sixty years now.
A shed in 2023
In 2023, Sid Hill cleared out the shed belonging to his grandmother, Janet Elizabeth Thornett. She had passed away shortly before. Among the tools his grandfather had once made himself (sometime in the 1950s or 1960s, in the garage, without a manual or blueprint) was a hand trowel. Its blade was curved, made entirely of steel, and still in perfect condition after decades of heavy use. No rust. No warping. No loose handle.
For most people, that would have been a special memory: something to cherish, but not necessarily to use. For Sid Hill, it was different. Hill is an ecological landscape designer, someone who approaches his work from the ground up. He knows what mycorrhizal networks are, why soil structure is fragile, and what happens when you dig too roughly through the earth with the wrong tools. He picked up the hand trowel, looked at the blade, and saw it right away.
The curved shape of the blade did something that conventional tools rarely do: it cut a clean, round, cylindrical planting hole, without twisting, prying, or compacting the surrounding soil. Just in, straight down, and done. The soil around the hole remained undisturbed. The mycelium intact. The structure preserved.
Hill took the hand trowel with him to work. And he started using it to garden every day.
Chelsea Flower Show 2024: Gold for the Soil
The RHS Chelsea Flower Show is the most prestigious horticultural exhibition in the world. Every year, the best garden designers of the moment present their work there, with gardens that must be both skillfully crafted and visionary. In 2024, Sid Hill was one of them.
His entry was called the Microbiome Garden. A garden that celebrated life beneath the soil: the fungi, bacteria, and microorganisms that help plants grow, store carbon, and sustain ecosystems. Not the flower or the tree as the star of the show, but what lies beneath. The invisible infrastructure of every healthy patch of earth.
To build that garden, Hill used his grandmother’s hand trowel. It was a conscious choice, not a sentimental one. The tool fit the garden’s philosophy: minimal disruption, maximum respect for what’s already there.
The Microbiome Garden won gold. And Hill received the Prince of Wales Trophy for Sustainable Horticulture, the highest award for sustainable gardening presented by the RHS. The hand trowel from Janet’s shed had proven its professional worth at the highest level in gardening.
When we heard this story, we knew what we wanted to do.
From Shed to Forge
Together with Sid Hill, we set to work developing a new tool, based on the design of his grandfather’s hand trowel but made using Sneeboer’s materials and techniques. Made entirely of stainless steel. Induction-hardened blade. And laser-welded from start to finish.
That last point requires some explanation, because it sets us apart from most providers in the industry. For many manufacturers, laser welding is an exceptional process, reserved for special projects or high-end production runs. For Sneeboer, it is the standard, integrated throughout the entire production process. The benefits are significant: it consumes 60 to 70 percent less energy than conventional welding, works two to ten times faster, and leaves behind a heat-affected zone that is up to two hundred times smaller. The latter is crucial for the precision of the final product: less heat means less distortion, less post-processing, and a cleaner weld.
We deliberately leave the weld seam visible. Not as a compromise or limitation, but as a choice. It’s proof of how the tool is made, with transparency as part of the craftsmanship. Anyone holding a Thornett Trowel can see exactly how the blade and handle are connected. No coating to hide anything. No finish to obscure the construction.
Seven iterations for a single weld
But before we got here, there was work to be done. The first prototypes of the Thornett were difficult for our craftsmen to make, especially the transition between the handle and the blade. At Sneeboer, that transition always has a sleek, polished finish. That’s not a decorative choice; it’s about ergonomics, about how the tool feels in your hand, about whether you can still work comfortably after an hour of gardening. Getting that transition right with the Thornett blade’s specific profile turned out to be a technical challenge that we had initially underestimated.
We had brought twenty prototypes to Chelsea 2025. They sold out on the first day. The market interest was undeniable. But production wasn’t ready yet.
At that point, we could have made two choices: lower our quality standards to deliver faster, or put more pressure on our employees to meet the volume. We chose neither. We went back to the drawing board. Seven iterations, spread out over several months. Each round involved adjusting, testing, and evaluating, until the seam could be made comfortably by our artisans, without compromising the final result in any way.
The market had to wait. That was the right decision, and one that reflects who we are. Sneeboer doesn’t make tools for a single season. We make tools that last for generations. That promise starts with how we manufacture, not how we sell.
What the Thornett Trowel Does for Soil Health
The curved blade is the heart of the Thornett Trowel, and the difference is in the details. Conventional hand trowels are flat or slightly curved, designed for scooping and leveraging. That works fine for many tasks. But when planting, that motion has a side effect: it compacts the soil around the planting hole, cuts through mycelium, and disrupts the aggregates, the small, porous clumps that keep the soil structure healthy and retain water.
The Thornett Trowel enables a different kind of movement. The curved blade cuts a clean, cylindrical planting hole, vertically, without prying or twisting. The soil around the hole remains completely intact. The mycorrhizal networks, the underground connections between plant roots that exchange nutrients, store carbon, and make plants more resilient, remain undisturbed. Whatever you plant goes into the ground without disturbing the soil around it.
For those who garden according to no-dig principles, this is no minor matter. It’s the reason you choose this tool over another. The same applies to those who are consciously working on soil restoration: less digging, more building up. The Thornett Trowel isn’t just a durable hand trowel. It’s a hand trowel that works with the soil rather than against it.
Technical specifications: 55 centimeters long, 700 grams, made entirely of stainless steel. It feels in the hand just as a Sneeboer tool should: well-balanced, precise, substantial without being obtrusive. It requires no strength; it requires attention.
Named after Janet
Every tool needs a name. We had no doubt about what that name should be.
Not the name of a designer, not that of an award, not that of a concept. The name of the woman whose husband made a hand trowel that served her well throughout her life, and that, after her death, found its way to us through her grandson. Janet Elizabeth Thornett. The Thornett Trowel.
Every Thornett Trowel comes with a 50-year warranty on the steel. But our true expectation goes beyond that. Made entirely of stainless steel: no coatings, no composite parts, no screws or rivets that come loose over time. If something ever goes wrong (and with this tool, we don’t expect that to happen), it can be repaired. By a professional, through welding, or by re-sharpening. It won’t be thrown away.
Janet’s husband’s hand trowel was still working after sixty years. That’s not just a marketing story. It’s proof of what’s possible when you make tools with a genuine focus on the end result: not on the price, not on the delivery time, but on what will still be in the user’s hand in their garden twenty, thirty, or forty years from now.
We’re proud of this tool, of the story behind it, of the artisans who make it, and of our collaboration with Sid Hill, who made this possible. The Thornett Trowel is not a limited edition, nor is it a tribute that will disappear after a single run. It’s a permanent part of our lineup, made to last, just like the hand trowel that inspired it.
Made for those who take the ground seriously, and for those who come after them.
