should look into optician's tools.
Cutters for music wire, tempered
springs, and other hard wires differ
from Ordinary cutters. While soft
copper wire flows and is pinched Off
when cut, hard wires break in tension
before the cutting edges actually
meet. Manufacturers worry more
about hardening the edges rather
than about having them meet perfect-
ly, as they seldom meet before cutting
through. And, since this kind Of
cutting imposes extremely high
stresses on the edges, they are a lot
blunter than ordinary cutters, and the
jaws are stronger.
Hard-wire cutters are made in
diagonal and end-cutter models. Since
cutting hard wire is often a two-hand
job, for heavy-duty applications they
are also made With compound lever-
age action and return spring.

be two or more
positions to allow the tool to grip
