Clips the Tip and Not the Quick All nails are slightly different on every pet, although most are similar in size and shape on a given pet. The first time you use Zen Clipper Precise, observe that the quick of the nail, the red part that has the blood supply, won’t be cut by the blade. Just a few tries and you’ll be using the Zen Clipper confident that it “Clips the Tip and Not the Quick”. Zen Clipper is especially helpful for pet owners with limited near vision since it will prevent you from cutting off too much of the nail, even if you cannot see up close. ERGONOMIC DESIGN WITH YOU AND YOUR PET IN MIND – with a cushioned, non-slip handle for your comfort and stainless-steel blades designed to shear the nails with a clean-cut; it does not crush the nails like conventional clippers – no jagged edges or need to file the nail
