which illustrates the preferred embodiment of the present
invention, A generally designates a nail clipper comprised
of a pair of registering, normally lower and upper jaw
members 1, 2 formed of suitable spring steel, which at
their outer ends (being the ends remote from a nail
being clipped) are in superimposed surface-wise abut
ment and secured together in such state as by a rivet

form, construction, arrangement, and combination of the
several parts of the nail clippers may be made and sub

Having thus described my invention, what I claim and
desire to secure by Letters Patent is:
1. Nail clippers for creating a substantially central out
wardly opening indentation in a nail to be clipped for

relieving pressure of lateral growth components of the
divergence and thereby being urged apart through their
nail, ‘comprising E?-I‘St and second jaws adapted for move

edges, the cutting edge of each jaw being comprised of a 15
pair of symmetrical lateral portions extending transversely
of said jaws, said lateral portions being of equal extent,
and an intermediate portion projecting endwise of said
jaws beyond the said lateral portions, said intermediate
portion having a pair of straight side components in con
verging relationship for meeting at a point on the longitu
dinal center line of the clippers spacedly forwardly from
said lateral portions.
