At Hill and Hide, we believe that quality should be more than a promise. It should be something we can demonstrate.
We carefully select the materials used in our belts, dog collars, leads and bags, with strength, durability and longevity central to our approach.
But we wanted to go a step further.
Rather than simply describing our English bridle leather as strong, we decided to put a sample of our leatherwork through an independent tensile strength test.
The result was 421 kg of force.
Why We Decided to Test Our Leather
English bridle leather has been trusted for generations in demanding equestrian applications, where material quality and dependable construction are essential.
At Hill and Hide, we use premium Sedgwick English bridle leather, selected for its strength, character and traditional finish.
We wanted to better understand how our leather and stitching would perform when subjected to a controlled pulling force.
It wasn’t about making an exaggerated claim or suggesting that any leather product is indestructible.
It was about putting our craftsmanship to the test.
An Independent Strength Test
In September 2026, we arranged for tensile testing to be carried out by Certex in Great Yarmouth, Norfolk.
The test involved five prepared specimens made from approximately 4 mm thick Sedgwick English bridle leather, measuring 1.5 inches wide.
Each specimen featured folded leather sections secured using stitching and adhesive, reflecting techniques used in our leatherwork.
The samples were then subjected to increasing tensile force using specialist testing equipment.
The purpose was to examine the strength of the prepared leather assemblies under controlled conditions.
The Result: 421 kg
During testing, one of our prepared specimens reached a force equivalent to 421 kilograms-force, approximately 4.13 kilonewtons.
For a relatively narrow strip of leather, it was a remarkable result to witness.
It provided a tangible demonstration of the strength achievable through carefully selected leather and considered construction techniques.
Importantly, the figure represents the result of a particular test specimen under specific conditions. It is not a certified safe working load for our finished belts, collars, leads or bags.
Nevertheless, it reinforced our confidence in the materials and methods we choose.
Why Stitching Matters
The quality of leather is only part of the equation.
How that leather is joined, secured and finished also contributes to the strength of the completed assembly.
For our belts and dog collars, we use traditional saddle stitching, a technique valued for its durability and ability to secure leather components.
The test specimens incorporated multiple rows of stitching alongside adhesive, allowing us to observe the performance of a prepared leather assembly rather than leather alone.
It’s another reminder that the details often hidden within a finished product can be just as important as those visible on the outside.
Made for Decades, Not Seasons
We don’t believe leather goods should be treated as disposable accessories.
Our aim is to create products that can accompany their owners for many years, developing character through use while remaining practical and dependable.
Independent testing is one way of exploring the performance of our materials and craftsmanship.
It doesn’t replace careful design, proper use or ongoing maintenance, but it provides another level of understanding about what goes into our products.
For us, the 421 kg result represents more than a number.
It represents our willingness to question, examine and continually improve what we make.
