I prefer the ARS hoof trimmers over the orange handled trimmers. This is ONLY because the red handled ARS trimmers are made from a hardened steel and will hold up to more trims and more sharpenings.
For the amount of hooves my trimmers see, I needed to spend the extra cash and get the better blade. I used to swear by the orange handled trimmers, but I trim professionally and was spending more $$$ on sharpeing services then I wanted to with the orange handled ones.
The orange handled trimmers are AWESOME if you are simply trimming your own herd and not going around trimming multiple herds of animals.
