Types of Wire Used
- Preformed, manually or with pliers.
- Tensioned, held tight by a frame with springs or (equivalently) by a bow. Many indicate a preference for single-strand stainless steel wire over nichrome wire, in diameters ranging from .008 inches(0.2032mm) to .020 inches(0.508mm) for frame-tensioned cutters. Musical instrument strings and leader wire used for fishing lures are readily available and inexpensive. Commercial cutting equipment often uses the nickel-based alloy wire Rene 41, a high-strength alloy which maintains most of its tensile strength at cutting temperatures.

Famous quotes containing the words types of, types and/or wire:
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“Constantly risking absurdity
and death
whenever he performs
above the heads
of his audience
the poet like an acrobat
climbs on rime
to a high wire of his own making.”
—Lawrence Ferlinghetti (b. 1919)
