CAUTION: CLIPPING NAILS REQUIRES GOOD SENSATION AND COORDINATION
Notice the emery boards in the large nail clipper held by pegs that are tightened by hand. I use these emery boards often to remove sharp points at the corners of my nails. This is safer than trying to get the clipper into these tight spaces. The clipper came with four emery boards, but replacing them will be a challenge. All the stores near my home sell only wide, thick boards (pink board) that do not fit in the clipper. The Internet sells short 4 inch emery boards except for this link.
My sound hand cuts nails on my affected hand with a regular nail clipper. Spasticity in my affected hand makes my fingers curl. To straighten them, I prop them one-at-a-time on a the edge of an opened drawer. The open drawer allows my sound hand to get low enough to get a good cutting angle. I put a piece of non-slip shelf liner under the finger to keep it from slipping, but the shelf liner got in the way when I photographed my hand.
Bottom Line: I cringed when I learned the large nail clipper costs $37.50, but nails do not stop growing so I do not have a choice.
