The thing that stops most people trimming their own pet's nails is the quick, the blood vessel running down the centre of the nail, and the memory of catching it once. On a pale nail you can see it as a pink shadow, but on a black one you are guessing. A light shining through the nail from behind changes that: it makes the darker core visible on all but the thickest nails, so you are cutting to something you can see.

That is what the built-in LED does here, and it is the reason to choose this over a plain pair of clippers. The blades themselves are sharp, which matters because a blunt clipper crushes the nail before it cuts and makes the whole experience unpleasant enough that the animal remembers. A grinder on the same tool takes the sharp edge off afterwards, so nails do not catch on carpet or scratch skin, and it lets you take a nervous animal's nails down in small passes rather than one committed cut.

Who it's for: Owners doing nails at home between grooms, especially anyone put off by dark nails where the quick cannot be seen.
