What it is Filled

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, commonly have steel blades with ground edges but can use other blade materials, and are among the most common household and professional tools.

Why it exists Filled

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.

Distinguishing features Filled

  • Pivoted shearing action
  • Many specialised forms
  • Right and left-handed versions
  • Ancient origin

What robots and AI may and may not do Filled

Must not

  • Leave scissors within reach of young children.
  • Run or move quickly with open blades near people.
  • Use scissors on a person's hair, skin or body without consent.
  • Use surgical scissors outside a clinical setting by qualified people.

Only with a human decision

  • Cutting near a person's body, such as hair, bandages or clothing.

May

  • Explain kinds of scissors and their uses.
  • Advise on safe use, carrying and storage, especially around children.
  • Assist with scissors only within applicable safety rules and authorization.

Moral aspects Filled

  • Scissors are everyday tools that cause frequent cuts, especially to children.
  • Cutting someone's hair or clothing without consent violates their dignity.

Who is affected

  • Children
  • Users
  • People having their hair cut

Owners Filled

Steward

The person who keeps them.

  • Two crossed steel blades pivoted at a screw, with finger loops or handles.

Capabilities and actions required Filled

  • relay materials and manufacture
  • relay safety and standards
  • distinguish from related tools

Open questions

  • Should surgical scissors and garden pruners be separate entries?
  • How should product standards be linked?
  • The registry entry has merged aliases naming specialised kinds; should they be split off?
