working portions thereof, thus resulting in appliances
which are more etficient in operation and more durable
in use.
Among the other objects and advantages of improved
The present invention is directed to improvements in
cutting appliances, and more specifically, to cutting ap
pliances of the type normally referred to as nippers, and
finding their greatest utilization as manicure appliances.

thereof, the blades of the end portion 20 contacting those
of the end portion 18 in edge-to-edge relation when the

A cross member 36 extends trans

on the lever 32 immediately adjacent the inner end of

going portions of the description of the `lever 32 and bolt
24 will be seen «to provide a means whereby the lever
arm, when held in the position illustrated in FIGURE

What is claimed is:
A manicure appliance comprising a main body por
tion including a pair of elongated substantially superim
posed spring arms, rivet means securing said arms to one
another and passing therethrough adjacent one of their
pairs of ends with the other ends of the arms being nor
mally biased -away from one another, said arms at their
outer ends having substantially fla-t end portions normally
biased apart, said end portions being bent to be substan
trated in FIGURE 6 wherein it is seen that the lever 32

is inverted to the position of FIGURE l, that is, with the 60 edge and lateral side edges, cutting blades on the lateral
lug 38 bearing directly against the outer surface of the
side edges of the respective end portions adjacent to but
