The idea
The idea for the Soletech Dehorner began while studying veterinary science at Massey University. During a practical class at the Large Animal Teaching Unit (LATU), Associate Professor Kevin Lawrence challenged me to come up with a better way to dehorn cattle.
It was clear the process was physically demanding, time-consuming, and relied on outdated tools like the traditional wire saw.
Early development
During lockdown, I began working on early concepts in the shed. The goal was simple, make the process easier and more efficient.
One of the key ideas was adapting the cutting motion to be powered mechanically, rather than manually.
Building the prototype
The first prototype was rough and built by hand. I then partnered with Mike from MWDesign, who helped take the concept further.
Using CAD design, 3D printing, and CNC machining, we developed and refined the tool through more than 20 iterations, testing, breaking, and improving each version.
First real-world use
The first successful use was alongside Dr Garth Riddle from Bay of Islands Vets. It quickly became clear how effective and easy it was to use in practice.
Field testing
We then produced a small batch of tools and sent them to veterinarians across New Zealand.
These early users collectively dehorned over 200 cattle, providing valuable feedback that helped refine the design further.
After several years of testing and improvement, the Soletech Dehorner is now being used by veterinarians looking for a faster, more efficient way to perform the procedure.
