Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain scissors and their kinds, relay design, materials and safety, identify specialised forms for trades, and distinguish scissors from shears, knives and cutters.

A hand-operated cutting tool with two pivoted blades that shear material between them when the handles are closed, made in forms for paper, fabric, hair, surgery, kitchen use and gardening, where larger versions such as shears, loppers and pruners cut branches and grass; scissors have been used since antiquity, are manufactured from steel with ground edges, and are among the most common household and professional tools.

What it is for: Cutting sheet materials, fabric, hair, plants and more.

It can be explain kinds and design; relay materials and manufacture; relay safety and standards; distinguish from related tools.
