Zwilling J.A. Henckels Ultra-Slim Nail Clipper do an excellent job. The construction and design of these clippers make it that they take up a  very minimal amount of space. Per following the illustrated instructions on the packaging my husband and I were able to figure out how to properly wield these for trimming finger and toenails. You simply slide the top part toward you to unlock it, then push that part all the way away from you, and then back toward you again to put the clippers into a cutting position. Closing the clippers is just as easy as opening them, once you get the hang of it.
