I would see if your doctor has or knows where to a calalog. If you have access to a PT or OT, they shoud also have catalogs. The therapist might also let you try using different gadgets before buying them. Hygene concerns may not allow you to return the clippers If you have poor circulation or reduced sensation, I'd reconsider doing it on your own. I could never use clippers & used to tear them off w/ my fingers. Both big toenails were removed a few yrs ago after being inghrown. A have a (guy) friend who goes to a nail salon.
