I have large hands and these trimmers fit my hand well and were Razor Sharp. Took very little effort to trim my goats hoofs and left nice ,clean hoof edges. If cleaned with a disinfectant and dried they do not rust.
I've tried really hard to make these work, but I'm giving up and buying something more expensive instead. They're pretty much worthless and you'll just end up pinching your fingers and hurting your animals.
