This one is for cutting the nails on your good hand!

Slide your nail into the clipper, and use the rest of your fist to press down.

Doing your thumb is more challenging, because it’s hard to use the weight of your fist while your thumb is between the jaws of the clipper! It takes a few tries, but I still recommend this gadget.
