Fingernail clippers are a
devilishly ingenious use of
levers and
applied force used to trim
fingernails to stop them from getting
unmanageably long and
lethal. Using a combination of levers, it closes a
blade with enough force to cleanly cut your
fingernails.
If you wish to clip your toenails, you either need the big brother to fingernail clippers, toenail clippers, or you need really small feet.
