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.

“The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.”
—Loris Malaguzzi (1920–1994)

“God, I am caught in a snare!
I know not what fine wire is round my throat;
I only know I let him finger there
My pulse of life, and let him nose like a stoat
Who sniffs with joy before he drinks the blood.”
—D.H. (David Herbert)
